High-energy Human Milk Diets in the First Two Weeks After Birth to Reduce BPD in Extremely Preterm Infants

This Phase II, parallel-group, masked, randomized clinical trial aims to evaluate whether a DHA/ARA-enriched, fortified human milk diet administered during the first 14 days of life reduces respiratory morbidity and improves lung function in extremely preterm (EPT) infants (born at ≤28 weeks gestation).

Improve the Survival Without Morbidity of Extremely Preterm Infants (PREMEX)

The intervention proposed is a new organization of care, based on the EXPRIM (EXtrem PRematurity Innovative Management) protocol, involving early, standardized, and multidisciplinary management of women hospitalized for a risk of extremely preterm birth and their children. It will take place in each perinatal network for all pregnant women hospitalized between 22 and 26 weeks with a risk of preterm delivery. Setting up the protocol requires taking into account the parents' time and timing issues, and its potential for change, to plan the implementation of the protocol, especially the degree of emergency of the situation and the probability of imminent delivery. The follow-up collected for this study will take place: * At D4 post-delivery: A questionnaire about the parents' experience of the information delivered and the decisions made will be given to and collected from the parents * At Day 28, post-delivery: A questionnaire about the parents' experience of care for their child will be given to and collected from the mother and the co-parent. * At the child's discharge from the hospital, or if he or she dies in the hospital: * Collection of clinical data (principal endpoint) from data in the medical file. * Data to measure practices and adherence to the intervention will be collected * When the child reaches the corrected age of 2 years: * a short questionnaire will be completed by the physician caring for the child at the corrected age of 2 years. The data collected will concern motor and sensory development, in particular, cerebral palsy, blindness, and deafness.. * Information about the child's development will also be collected with a questionnaire including a standardized assessment scale, he PARCA-R questionnaire (Parent Report of Children's Abilities-Revides), which the parents will complete.

NICU Antibiotics and Outcomes Trial

The goal of the NANO trial is to study the longstanding clinical practice of empirically administering intravenous antibiotics to extremely low birthweight (ELBW) infants in the first days of life. In this 802-subject multicenter placebo-controlled randomized clinical trial, the hypothesis to be tested is that the incidence of adverse outcomes is higher in babies receiving empiric antibiotics (EA) in the first week of life compared to babies receiving placebo. The study targets a population of ELBW infants in whom the clinical decision to use or not use EA is currently most challenging -- infants that are clinically stable that did not have a known exposure to intraamniotic infection and were not born preterm for maternal indications. The primary outcome is the composite outcome of late-onset sepsis (LOS), necrotizing enterocolitis (NEC), or death during the index hospitalization. Secondary safety outcomes will include total antibiotic days, days to full enteral feedings, and common morbidities in preterm infants that have previously been linked to EA, e.g. retinopathy of prematurity and bronchopulmonary dysplasia. Weight and length z-score, and head circumference, are standard measures to be collected weekly by clinical team per a standardized protocol.

Single-dose Prophylactic INdomethacin in Extremely Preterm Infants

In Canada, about 900 babies each year are born very early (\<26 weeks of gestation) and have a high chance of dying or having a serious bleed in the brain. Families of these extremely preterm babies consider preventing severe brain bleeding as critical to their child's health and well-being. A medicine called indomethacin, when given intravenously in 3-doses, is known to reduce severe brain bleeding. But use of this drug is variable among clinicians working in the neonatal intensive care unit (NICU) due to (a) its side effects on the gut; (b) possible harm when used with other medications; (c) a notion that despite reducing brain bleeds, the child's long-term brain development is not improved. Emerging evidence suggests that a single low-dose indomethacin regimen may be equally effective in reducing severe brain bleeding as compared to a traditional 3-dose regimen. The investigators propose a blinded randomized controlled trial, a study design where babies born \<26 weeks will be randomly assigned within 12 hours of birth to either a single dose of intravenous indomethacin or similar looking placebo in the form a saline solution. The study will test if a single dose indomethacin regimen is effective in improving survival of these babies without the devastating complication of severe brain bleeding. In this study the care providers and researchers will be unaware as to which baby receives indomethacin and which baby receives placebo to ensure no one's expectations or biases can influence the results. The investigators will conduct the study in multiple NICUs across Canada, the United States and Australia in 2 phases: First, an internal pilot phase that will enroll 104 babies born \<26 weeks or \<750 g birth weight over a period of 1 year. If the investigators are successful in achieving their target enrolment in the pilot phase, they will move on to the second phase and continue enrollment up to a total of 500 babies born \<26 weeks or \<750 g birth weight over a period of 3 years. The total of 500 babies will include the 104 babies enrolled in the first phase of the study. This study will help the investigators determine in the most unbiased way whether a single dose of indomethacin given immediately after birth in the smallest babies born \<26 weeks of gestation can safely and effectively reduce severe brain bleeding.

Ventilator Pressure and Optimization of Compliance and Hemodynamics

In preterm infants \< 34 weeks' gestation at birth receiving respiratory support with invasive positive pressure ventilation, the positive end-expiratory pressure (PEEP) of best compliance will increase the cardiac output and improve oxygenation. This study may emphasize using point-of-care echocardiography along with electrical impedance tomography (EIT) to optimize ventilator settings in preterm infants. Infants will be randomized to a 4-hour crossover period of increasing and decreasing PEEP in random order from baseline to determine compliance, oxygenation, and cardiac hemodynamics at each step using echocardiography (ECHO) and EIT measurements. There will be a 15-minute washout period after changes prior to data collection.

Dopamine vs. Norepinephrine for Hypotension in Very Preterm Infants With Late-onset Sepsis

Fluid-unresponsive hypotension needing cardiotropic drug treatment is a serious complication in very preterm neonates with suspected late-onset sepsis (LOS; defined as culture positive or negative bloodstream infection or necrotizing enterocolitis occurring \>48 hours of age). In Canada, \~250 very preterm neonates receive cardiotropic drugs for LOS related fluid-unresponsive hypotension every year; of these \~35-40% die. Unlike for adult patients, there is little evidence to inform practice. While several medications are used by clinicians, the most frequently used medications are Dopamine (DA) and Norepinephrine (NE). However, their relative impact on patient outcomes and safety is not known resulting in significant uncertainty and inter- and intra-unit variability in practice. Conducting large randomized trials in this subpopulation can be operationally challenging and expensive. Comparative effectiveness research (CER), is a feasible alternative which can generate high-quality real-world evidence using real-world data, by comparing the impact of different clinical practices. Aim: To conduct an international CER study, using a pragmatic clinical trial design, in conjunction with the existing infrastructure of the Canadian Neonatal Network to identify the optimal management of hypotension in very preterm neonates with suspected LOS. Objective: To compare the relative effectiveness and safety of pharmacologically equivalent dosages of DA versus NE for primary pharmacotherapy for fluid-unresponsive hypotension in preterm infants born ≤ 32 weeks gestational age with suspected LOS. Hypothesis: Primary treatment with NE will be associated with a lower mortality Methods: This CER project will compare management approach at the unit-level allowing inclusion of all eligible patients admitted during the study period. 16 centers in Canada, 2 centers in Ireland, 1 center in each of Israel, Spain and the UK, and 6 centers in the United States have agreed to standardize their practice. All eligible patients deemed circulatory insufficient will receive fluid therapy (minimum 10-20 cc/kg). If hypotension remains unresolved: Dopamine Units: start at 5mics/kg/min, increase every 16-30 minutes by 5 mics/kg/min to a maximum dose of 15 mics/kg/min or adequate response Norepinephrine Units: start at 0.05 mics/kg/min, increase every 16-30 minutes by 0.05 mics/kg/min to maximum dose of 0.15/mics/kg/min or adequate response

Delayed Cord Clamping With Oxygen In Extremely Low Gestation Infants

This study is being conducted to compare the incidence of preterm infants (up to 28+6 weeks GA) who achieve a peripheral oxygen saturation of 80 percent by 5 minutes of life (MOL) given mask CPAP/PPV with an FiO2 of 1.0 during DCC for 90 seconds (HI Group) to infants given mask CPAP/PPV with an FiO2 of .30 during DCC for 90 seconds (LO Group).

Open Lung Maneuvers During High Frequency Oscillatory Ventilation in Preterm Infants

To assess whether stepwise oxygenation-guided lung recruitment at regular intervals reduces the oxygen saturation index (OSI = Mean Airway Pressure × Fraction of inspired Oxygen × 100 / peripheral Oxygen Saturation, OSI = MAPxFiO2x100/SpO2) averaged over high frequency oscillation ventilation (HFOV) time in extremely preterm infants.

Folic Acid Supplementation to Reduce Anemia in Extremely Preterm Infants

Anemia of Prematurity (AOP) is very common in extremely preterm infants and often leads to blood transfusions. Folic acid, essential for growth and DNA synthesis, is deficient in premature infants. Despite the adoption of folic acid supplementation, evidence supporting its effectiveness in preventing AOP remains scarce. Recommendations for folic acid intake exceed what's naturally found in breast milk, particularly for extremely low birthweight infants. Practices regarding folic acid supplementation vary widely, prompting the need for research. The FACINATE trial aims to determine if additional folic acid supplementation improves hemoglobin levels and reduces late blood transfusions in extremely preterm infants, a question not addressed in current literature.

Stockholm Preterm Interaction-Based Intervention

Extreme premature Children will at discharge from Karolinska Hospital and Södersjukhuset in Stockholm be asked to participate in a study, examining the effects of a home-visit based post-discharge program aiming at facilitating the interaction between infants and parents, improving the development of the children, and the parental mental health. The study is a randomized controlled Trial (RCT), hence 50% of the participants will be offered treatment as usual (TAU) with addition of an extended follow-up program. The interaction-based program consists of one initial visit at the hospital followed by nine home-visits and two telephone calls during the child's first year of life. The interventionists are skilled Healthcare professionals with several years of experience from caring for premature infants and their parents. All interventionists have successfully completed a one year further education program, delivered one day per week and containing theoretical lectures, practice with actual cases, supervision on the cases, visits to the different parts of the neonatal care chain and discussions with a representative from the premature family association Sweden.

Early Intervention Based on Neonatal Crawling in Very Premature Infants at Risk For Neurodevelopmental Disorder

Extreme prematurity is constantly increasing according to the World Health Organization. However, methods to train premature infants at risk of disability is sorely lacking. The goal of this project is to overcome this problem. In previous studies, the investigators discovered that promoting the crawling of typical newborns on a mini skateboard, the Crawliskate (a new tool that the investigators designed and patented EP2974624A1), is an excellent way to stimulate infants' motor and locomotor development. This method is a promising way to provide early interventions in infants at heightened risk for developmental delay, such as premature infants. The specific objective of this study is to determine if early training in crawling on this mini skateboard will accelerate motor (particularly locomotor) and/or neuropsychological development in very premature infants identified as high risk for developmental delay. Methodology: The investigators will study and follow two groups of very premature infants born between 24 and 26 weeks of gestational age or born between 26 and 32 with major brain lesions. These infants will be recruited before their hospital discharge at the NICU. After their discharge from the hospital, one group of infants will be trained at home by their parents under the supervision of physiotherapists to crawl on the Crawliskate every day for 2 months (Crawli group), and one group of infants will receive regular medical care (Control group). All infants will be tested for: 1)their crawling proficiency on the Crawliskate at term-equivalent age (just before training for the trained groups) and at 2 and 6 months corrected age (CA, i.e., age determined from the date on which they should have been born), 2) their motor proficiency between 2 and 12 months CA (2D and 3D recording of head control, sitting, crawling, stepping, walking) and 3) their neurodevelopmental, motor and neuropsychological development between 0 and 28 months CA: BSID III edition, ASQ-3, Amiel-Tison's Neurological Assessment, Prechtl Assessment of general movements. One more ASQ-3 questionnaire will be provided at five years. Expected results: The first research hypothesis is that premature infants trained daily to crawl (for two months after discharge from the NICU) will acquire proficient crawling patterns and develop earlier and more effective motor and neuropsychological development than premature infants who receive no training.
