EMDR Therapy in Preterm-Born Infants With Post-Traumatic Stress Symptoms

This study examines a trauma-focused treatment for very young children who were born prematurely and developed post-traumatic stress related symptoms after medical care. Preterm infants often experience stressful events in the hospital, which can affect their emotional and behavioral development. In this study, an adapted form (storytelling) of Eye Movement Desensitization and Reprocessing (EMDR) therapy was used with preterm born children aged 0 to 2 years. The treatment was delivered in a small group of participants, and changes in post- traumatic stress symptoms, sleep, emotional functioning, parental PTSD symptoms and perceived bonding and parent-infant interaction were monitored over time using parent reports. The aim of the study is to evaluate whether this early intervention (EMDR, storytelling) is feasible, well accepted by families, and potentially effective in reducing post-traumatic stress related symptoms in this vulnerable population.

Detection of Respiratory Events Using Acoustic Monitoring in Extremely Preterm Infants

Extremely preterm infants, born before 29 weeks of pregnancy, often face breathing difficulties, also known as respiratory events, due to their undeveloped lungs and respiratory systems. These respiratory events include pauses in breathing, shallows breaths, and irregular breathing patterns. These problems are most common right after birth but can continue for weeks, leading to extended hospital stays, higher medical costs, and potential long-term health concerns affecting the eyes, lungs, and brain. Currently, neonatal intensive care units (NICUs) use methods like measuring oxygen levels, heart rate, and electrical resistance in the chest to monitor for respiratory events. However, these methods have limitations. For instance, they cannot accurately measure airflow and do not distinguish between different types of respiratory events. As a results, some breathing problems might go unnoticed or be managed improperly. To address this, the investigators have developed a wireless acoustic sensor that uses advanced microphones and motion sensors to record airflow and chest movements. In initial tests with healthy preterm infants, this sensor proved reliable in detecting breathing patterns and airway obstruction, suggesting it could offer a more precise and non-invasive monitoring method. This study aims to assess how well this new sensor performs compared to existing methods in detecting and distinguishing different types of respiratory events in a high-risk group of extremely preterm infants. The investigators will track respiratory patterns in preterm infants at various stages between 32 and 44 weeks of age. By comparing the new sensor's performance with currents standards and gold-standard methods, the investigators hope to improve the management of these respiratory events and reduce the related health risks.

Optimizing Early Nutrition Management of Extremely and/or Very Preterm Infants

A clinical quality improvement bundle on early nutrition supplementation is developed to improving the clinical outcomes (including growth, organ function, and neurodevelopment outcomes) of extremely and/or very preterm infants. This bundle consists of three aspects: individualized and precise human milk feeding, early enteral zinc supplementation, and routine parenteral carnitine supplementation.

Early Kangaroo Mother Care in Gambian Hospitalised Unstable Neonates

The mortality effect of kangaroo mother care in stable newborns \<2000g is well established but mortality effect in unstable newborns is not conclusively known. This pragmatic clinical trial aims to investigate the mortality and clinical effects of early continuous Kangaroo Mother Care (KMC) compared to standard care in mild-moderately unstable neonates \<2000g in a resource limited hospital setting.

Acoustics as a Metric of Airway Pressure in Premature Infants Using Bubble Continuous Positive Airway Pressure

This is an observational, proof-of-concept, feasibility study where 30 preterm infants on bubble CPAP with gestational age \< 32+0 weeks will be recruited from the neonatal intensive care unit (NICU) at the Montreal Children's Hospital. The study's main goals are: 1. To determine the relationship between ambient bubbling sounds and delivered pressures in preterm infants on bCPAP. 2. To determine the relationship between transmitted bubbling sounds and airway pressures transmitted to the lungs of preterm infants on bCPAP. 3. To develop models to predict delivered and transmitted bCPAP pressures from the acoustic properties of bubbling sounds.

Early Prediction of Spontaneous Patent Ductus Arteriosus (PDA) Closure and PDA-Associated Outcomes

Patent ductus arteriosus (PDA), very common in preterm infants, is the delayed closure of a fetal blood vessel that limits blood flow through the lungs. PDA is associated with mortality and harmful long term outcomes including chronic lung disease and neurodevelopmental delay. Although, treatments to close PDA likely benefit some infants, widespread routine treatment of all preterm infants with PDA may not improve important outcomes. Left untreated, most PDAs close spontaneously. Thus, PDA treatment is increasingly controversial and varies markedly between hospitals and individual providers. The relevant and still unanswered clinical question is not whether to treat all preterm infants with PDA, but whom to treat and when. Treatment detriments may outweigh benefits, since all forms of deliberate PDA closure have potential adverse effects, especially in infants destined for early, spontaneous PDA closure. Unfortunately, clinicians cannot currently predict in the 1st month which infants are at highest risk for persistent PDA, and which combination of clinical risk factors, echocardiographic (echo) measurements, and serum biomarkers may best predict PDA-associated harm. The American Academy of Pediatrics has acknowledged early identification of infants at high-risk from PDA as a key research goal for informing future PDA-treatment effectiveness trials. Our objective is to use a prospective cohort of untreated infants with PDA to predict spontaneous ductal closure timing and identify echo measurements and biomarkers that are present in the 1st postnatal month and associated with long-term impairment. Our central hypothesis is that these risk factors can be determined to inform appropriate clinical treatments when necessary. Clinical, serum and urine biomarkers (BNP, NTpBNP, NGAL, H-FABP), and echo variables sequentially collected during each of the first 4 postnatal weeks will be examined. In addition myocardial deformation imaging (MDI) and tissue Doppler imaging (TDI), innovative echo methods, will facilitate the quantitative evaluation of myocardial performance. Aim 1 will estimate the probability of spontaneous PDA closure and predict the timing of ductal closure using echo, biomarker, and clinical predictors. Aim 2 will specify which echo predictors and biomarkers are associated with mortality and severity of respiratory illness at 36-weeks PMA. Aim 3 will identify which echo predictors and biomarkers are associated with 22- to 26-month neurodevelopment. All models will be validated in a separate cohort. This project will significantly contribute to clinical outcomes and PDA management by reducing unnecessary and harmful overtreatment of infants with a high probability of early spontaneous PDA closure, and will permit the development of outcomes-focused trials to examine the effectiveness of PDA closure in those "high-risk" infants most likely to receive benefit.

Taiwan Preterm Infant Database: Analysis and Comparison of Birth Conditions and Exploration of Prognostic Factors

The purpose of this study is to conduct a long-term follow-up of preterm infants with different birth conditions, aiming to provide data and resources for future care and to identify predictive and influencing factors related to their functional development over time. It is hypothesized that (1) preterm infants with varying birth conditions, such as birth weight and gestational age, will exhibit different developmental outcomes, and that the establishment of a Taiwan-specific preterm infant database is essential due to the lack of comprehensive local data and ethnic variations in gestational patterns; and (2) neonatal factors, including gestational age, birth weight, and postnatal complications (e.g., pneumonia, seizures, hypoxia), serve as potential risk factors influencing later developmental trajectories.

Early Lung Function Trajectories: Comparison Between Infants With and Without Intrauterine Growth Restriction.

During intrauterine life, some babies are smaller or grow less than expected. This fetal growth abnormality, called fetal growth restriction (FGR), can be diagnosed by ultrasound. Since there are currently no curative treatments for this condition, nor methods to optimize the growth of babies in the womb, the only effective strategy is intensive monitoring of fetal conditions, accompanied by early planning of delivery. The diagnosis of early FGR (i.e. diagnosed before 32 weeks of gestation) confers a greater risk of short- and long-term respiratory problems. The study aims to examine the association between parameters that can be assessed during pregnancy by ultrasound, such as the estimate of lung volumes, the thickness and contractility of the diaphragm, and cardiac kinetics, and any perinatal complications and respiratory function in the first years of life of premature infants, both with and without evidence of fetal growth pathology. Therefore, the study is divided into two phases: a prenatal and a postnatal phase. The study includes two groups of patients: 1. Study group: Fetuses and preterm infants with a prenatal history of FGR; 2. Control group: Preterm infants without a prenatal history of FGR followed during neonatal follow-up. Pregnant women with fetuses with FGR are followed at the Ultrasound clinics dedicated to Growth Pathology. These pregnancies usually receive weekly ultrasound monitoring, which includes a Doppler study of the maternal and fetal circulation and an estimate of fetal weight every two weeks. Cardiotocographic monitoring is also planned once or twice a week, depending on fetal well-being. The child will be assessed from a respiratory point of view during hospitalization and subsequently in the outpatient clinic, as required by clinical practice. He/she will undergo respiratory function tests. Visits are scheduled at 3, 6, 12 and 24 months of corrected age, during which at least two respiratory function tests will be performed. In addition, routine clinical data (personal data, medical history, blood tests, biological and instrumental tests) present in the medical record of the child will be collected. Data from preterm infants without fetal growth restriction will be collected after informed consent. These infants are routinely followed at our Institution and undergo clinical assessment and lung function tests in the first two years of life as previously indicated.

Positive Feeding of the Preterm Infant

The goal of this feasibility study is to assess the feasibility to implement a feeding strategy for preterm infants. The main questions it aims to answer are: * Is it feasible to implement the PoP-intervention in a level 3a category Neonatal intensive care unit? * Is the PoP-intervention acceptable for parents of preterm infants and health care personnel working in Neonatal intensive care unit? Parents of preterm infants and health care personnel will be asked to follow a protocol of a feeding strategy based on the preterm infants development and cues throughout the NICU-stay.

Clinical Impact of Non-invasive Neurally Adjusted Ventilatory Assist in Very Preterm Infants

This is a prospective observational study investigating the impact of NIV-NAVA on short-term clinical outcomes and long-term neurodevelopment in very preterm infants.

Air vs. Cutaneous Control Mode for Preterm Infants ≤ 32 WG in Incubators: Impact on Body Growth and Morbidity

Previous studies have shown that mortality and morbidity in preterm neonates are correlated with the fall in body temperature on admission. Hypothermia can be decreased by reducing body heat losses to the environment. The investigator research hypothesis is that a new calculation of the air temperature in the incubator would promote the newborn infant weight growth from the period between birth and day 10 of life compared to cutaneous mode. The secondary hypotheses assumes a decrease in the side effects usually observed in both morbidity and mortality. A software is used to calculate the body heat loss (BHL) of each individual preterm infant, and to propose a specific air temperature setting inside the incubator to reduce BHL to zero. This software has been validated in a previous pilot study (Degorre et al. 2015). This study aims to compare the energy costs of providing incubated preterm infants born between 25 and 32 weeks of gestation with homeothermia using either specific individualized air temperature control (ATC) or skin servocontrol (SSC).

Development, ADL, Participation, and Quality of Life in Preterm Infants: Longitudinal Research

The three fundamental goals of early rehabilitation for preterm infant after leaving NICU are: optimizing function within each child's prognostic potential, preventing the development of secondary conditions that impact life-long health, and promoting children's participation and qualities in their lives. Understanding knowledges of these developmental patterns of Function and Participation in Life Activities (FPLA) and HRQOL may be helpful for anticipating and managing the problems. This study hypothesizes that the course of developmental patterns in FPLA and HRQOL of preterm infant evolve with their age. The functional recovery levels include developmental function, health, activity, participation, and quality of life (QOL). Since the previous plan only passed one year and encountered the COVID-19, the number of cases was not as expected. Therefore, this study will use the previous plan to test the functions of reliability, validity, and the evaluation of daily life participation to investigate the long-term performance of premature infants. Vertical development model under tracking. In addition, it is also expected to identify predictors related to the prognosis of preterm infants and compared with the healthy children of the Taiwan Early Childhood Development Survey Database (KIT) to find out the key differences in the developmental function and health of premature infants and healthy children. This study is a three-year longitudinal study of premature infants. It was carried out for three years. 60 full-term children aged 0-3 years and 150 premature infants aged 0-3 years were collected. A total of 210 children underwent a three-year period study. During the follow-up period, in addition to the initial evaluation, each subject will be followed up at 3 months, 6 months, 12 months, 18 months, and 24 months, toddlers( \>24months) will be followed up once a year according to the age of KIT's admission, and we will provide caregiver assessment report. We believe the results of this study will improve and support services provided to preterm infants.

Gut Microbiota of Preterm Infants and Full-term Infants at Early Life

The aim of this study is to obtain a longitudinal view of the gut microbial establishment of a cohort of 51 preterm (PT) infants compared to 50 full-term (FT) infants from birth to 90 days of age, and to identify key clinical factors that affect the establishment of neonatal microbiome. The hypothesis of the investigators is that the gut microbiota progression of PT group and FT group is different in diversity and composition. Antibiotics and its usage duration is likely the main factor disturbing the colonization and development of the gut microbiome of PT infants.

Does Timing Matter? Supporting Play, Exploration, and Early Developmental Intervention

Infants born very preterm (≤28 weeks of gestation) are at high risk of having developmental disabilities including cerebral palsy, coordination impairments, attention deficit and learning disabilities. Impairment including reduced postural control, movement variability, visual motor skills, and motor learning are common during the first months of life and are associated with later developmental disabilities. However, infant born very preterm rarely receive evidence based therapeutic intervention in the first months of life when basic science and animal intervention studies suggest the greatest efficacy. Barriers to enrollment in services delay the onset of services and delivery models rarely support targeted preventative intervention or enhanced parent engagement during in the transition from the neonatal intensive care unit (NICU) to home. Targeted intervention supporting postural control and motor learning in the NICU have resulted in short term motor gains. Interventions that enhance parent's ability to read their infant's cues and provide engagement opportunities improve maternal mental health and infant social and cognitive outcomes in the short-term. The purpose of this randomized clinical trial is to evaluate the efficacy of an intervention that combines evidence based motor intervention and parent engagement to enhance the parent's ability to provide daily motor and cognitive opportunities resulting in improved motor and cognitive outcomes. Supporting Play Exploration and Development Intervention (SPEEDI) uses guided participation to empower parents in reading infant's behavioral cues, identifying ideal times for interaction, and enriching the environment and learning opportunities. Parents participate in 5 session in 3 weeks while learning principles of engagement, readiness for interaction, and to provide early motor and cognitive learning opportunities. Parents provide 20 minutes of motor and cognitive play based enrichment daily for 12 weeks with bi-weekly physical therapist support. The parent is empowered to determine the infant's current abilities and advance the activities to the "Just Right Challenge" throughout the 12 weeks, likely continuing after the intervention. The efficacy of SPEEDI will be assessed during delivery at 2 time point; the transition from the NICU to home (around the infant's due date) and at 3-4 months of adjusted age (after the infants due date). Ninety infants will be randomly assigned to a Usual Care group, SPEEDI\_Early, or SPEEDI\_Later group. Group differences will be assessed in developmental outcomes on the motor and cognitive scales of the Bayley Scales for Infant and Toddler Development as well as the Early Problem Solving Indicator and Gross Motor Function Measure at the end of each intervention period, 12 and 24 months of age.
