This is an observational study in which only data from babies with retinopathy of prematurity (ROP) who are being treated with aflibercept (Eylea) in prefilled syringe (PFS) using a paediatric dosing device (PDD) are collected and studied. ROP is a condition that affects the eyes of preterm babies. It occurs when the baby's retina, the part of the eye that senses light, does not develop normally. This may result in vision problems, including blindness, if left untreated. Preterm babies are born before 37 weeks of pregnancy. ROP is more likely to develop in babies who are born before 32 weeks of pregnancy or weigh less than 1.5 kilograms at birth. Aflibercept is a drug that is injected into the eye. It works by blocking a protein called vascular endothelial growth factor (VEGF) which causes abnormal growth of blood vessels in the retina. Aflibercept in PFS given using a PDD is approved for the treatment of babies with ROP. The prefilled syringe will be fitted with an injection needle to give aflibercept. And a PDD is a tool used to give the right amount of aflibercept to children in a safe manner. Since there are other treatments which are commonly used for babies with ROP, the extent of use of aflibercept given using a PDD is unknown. The main purpose of this study is to: - find the number of preterm babies who are treated with aflibercept using a PDD in the UK - inform whether this number is enough to perform a study to learn about the long-term safety of aflibercept given using a PDD in babies with ROP An additional purpose of this study is to describe characteristics including age, sex, and race, and signs and symptoms of ROP observed in babies being treated with aflibercept using a PDD. The data will come from a database called the National Neonatal Research Database. The study will cover the period from March 2024 to March 2025, if the number of babies found is enough to perform the safety study. If not, data will be collected till April 2027. In this study only available data from preterm babies born during the study period are collected. No visits or tests are required as part of this study.
investigator is doing single armed clinical interventional study to treat premature ovarian insufficiency with autologous bone marrow derived mononuclear cells to be given systematically and locally to the ovaries under ultrasound guidance with experienced gynecologist and to look for the results including: laboratory evidence through hormonal study ultrasound proof of ovarian follicle development. premature ovarian insufficiency is characterized by early loss of ovarian function (less than 40 years of age) manifested by menstrual irregularity or amenorrhea with elevated levels of gonadotropin hormones and low estrogen and anti-Mullerian hormone. Autologous use of stem cells from bone marrow are alternative safe minimal manipulative products that can provide a solution to this clinical problem without the need for oocyte donation program.
Background: In premature babies, many organ systems are not fully grown and developed, including the lungs and respiratory muscles, so they will need breathing support to help them to breathe by preventing their tiny air sacs to collapse. This support commonly done by CPAP and Non-Invasive Positive Pressure Ventilation (NIPPV) therapy by giving some pressure and oxygen to their lungs through an interface placed on their noses. Both (CPAP and NIPPV) can be used as a support modality for respiratory distress syndrome, apnea of prematurity, and providing breathing support after extubation from the full mechanical breathing support. The CPAP supports the baby's immature lungs by delivering constant pressure to keep their lungs and breathing well supported. Whereas the NIPPV will use constant pressure in the background (similar to CPAP), and on top, it will give extra intermittent puffs at regular intervals to support the baby's breathing. The NIPPV is the most common choice by the clinicians when the traditional CPAP is no longer effective, to avoid the full mechanical breathing support and to protect the developing lungs. Studies suggested that NIPPV is better than the traditional CPAP in reducing the need of the baby to need full mechanical breathing support. This might be because the investigators tend to use lower pressures with CPAP (5-8 cmH2O) compared to relatively higher pressures with NIPPV. More recently, clinicians showed the safety of using equivalent higher CPAP pressures (>9 cmH2O) to what the investigators use in the NIPPV in preterm babies. One way to measure the support that the investigators are giving to the patient with the different devices is to measure the diaphragm activity, which the investigators call the Edi signal, using a special feeding catheter and a specific machine to measure it. The catheter is placed and used as a routine feeding tube but has sensors at the end to measure this Edi signal. One opening of the tube will be connected to a computer to record the Edi signals. The other opening of the tube will be used for feeding.
The VitDTracking study focuses on the relevance of maternal vitamin D levels and their association with prematurity, aiming to improve maternal and child health outcomes, particularly by reducing avoidable preterm births. In Portugal, vitamin D levels during pregnancy have never been studied. Epidemiological data from other countries reveal a high prevalence of vitamin D deficiency/insufficiency, especially in pregnant women. The hypovitaminoses prevalence remains high even with a supplementation dosage of 400 to 600 IU/day during pregnancy (dosage used in Portugal), which is considered as a suboptimal dose. This phenomenon is associated with adverse maternal and child outcomes, such as intrauterine growth restriction, preeclampsia, cholestasis, hypertension, and gestational diabetes as major causes of prematurity. Additionally, the Portuguese population has a higher prevalence of genome alterations that confer a lower capacity to produce vitamin D from sunlight exposure. These genetic characteristics are present in about 19% of the population, representing a prevalence four times higher than the European average (19% versus 4.75%), leading to a higher predisposition to vitamin D deficiency.
In this study, the investigators aim to validate a non-invasive marker of fluid-responsiveness in preterm infants (term below 37 gestational week) with acute circulatory failure based on standardized abdominal compression. This would allow physicians to identify which patient could benefit from a fluid expansion, thus avoiding a potentially useless or even dangerous fluid expansion, leading to fluid overload. To this end, the investigators will evaluate the diagnostic accuracy (sensitivity and specificity) of stroke volume variation induced by standardized abdominal compression for the diagnosis of fluid responsiveness (based on the gold-standard test: significant increase in cardiac index after fluid expansion).
Preterm infants (i.e. born before 37 completed weeks of pregnancy) often require additional care and are admitted to neonatal units. Readiness for discharge home typically requires a level of physiological maturity, such that an infant is: 1) able to breathe spontaneously without additional support; 2) able to maintain body temperature; 3) able to take all nutritional requirements orally; 4) weighs ≥1700 grams and is consistently gaining weight. Staying in the hospital longer than necessary can be detrimental to infants, stressful for families, and costly to the NHS. Reducing the length of stay by just one day would be meaningful to parents and could save the UK National Health Service (NHS) almost £25million per year. Currently little is known about whether, how long and why preterm infants stay in hospital beyond the point at which they are physiologically ready for discharge. This study will use data from babies' medical records from the whole of England and Wales to identify the age and postmenstrual age when preterm infants reach each of the physiological barriers to discharge and identify which physiological discharge barrier requires preterm infants to remain in hospital the longest. The study will quantify the difference between the time preterm infants become physiologically ready for discharge and actual discharge home and describe factors associated with extended stays.
The goal is to demonstrate the relationship of the circulating pool of T-regulatory lymphocytes in the mother's peripheral blood with populations in the placentas and to compare with controls, what is the difference in the expression of individual regulatory molecules of T-regulatory lymphocytes according to new paradigms. The proportional and functional characteristics of T-regulatory lymphocytes will be correlated with the composition of the intestinal and vaginal microbiota.
Previously, the investigators showed that preterm newborns are exposed chronically to very low radiofrequency levels in average while hospitalized in NICUs. Most of the infants were nevertheless frequently exposed to transient values above 1 V/m. The investigators also showed that an increase in RF exposure is likely to alter the activity of some neurophysiological functions and their regulatory systems in preterm newborns. The investigators hypothesize that above results are extremely specific to the location of the previous study and may be different in other NICU environments. This study will aim at quantifying RF levels to which preterm newborns are exposed during their stay in several NICUs spread across the French territory, and assessing its impact on the central and peripheral nervous systems. The first step of this study will be to quantify the precise, continuous and individual levels of daily RF exposure to which each recruited neonate is subjected during his stay in the different NICUs from birth to 1 week postnatal life. Infants' clinical data (medical history, nutrition, morphology...) will also be continually monitored. At 1 week postnatal life, the investigators will investigate cerebral activity (EEG) and autonomic nervous system activity (ECG, heart rate variability). The impact of RF will be evaluated by analyses of the relationship between exposure levels and the various parameters extracted from the neurophysiological investigation phase.
Before birth, the baby's lungs are filled with fluid and babies do not use the lungs to breathe, as the oxygen comes from the placenta. As delivery approaches, the lungs begin to absorb the fluid. After vaginal delivery, the umbilical cord is clamped and cut after a delay that allows some of the blood in the umbilical cord and placenta to flow back into the baby. Meanwhile, as the baby breathes for the first time, the lungs fill with air and more fluid is pushed out. However, it does not always work out that way. A baby born prematurely may have breathing problems because of extra fluid staying in the lungs related to the immaturity of the lung structure. Thus, the baby must breathe quicker and harder to get enough oxygen enter into the lungs. The newborn is separated from the mother to provide emergency respiratory support. Although the baby is usually getting better within one or two days, the treatment requires close monitoring, breathing help, and nutritional help as the baby is too tired to suck and swallow milk. Sometimes, the baby cannot recover well and show greater trouble breathing needing intensive care. This further separates the mother and her baby. A possible mean to help the baby to adapt better after a premature birth while staying close to the mother is to delay cord clamping when efficient breathing is established, either spontaneously or after receiving breathing help at birth. In this study, we intend to test this procedure in moderate or late preterm infants and see whether the technique helps the baby to better adapt after birth and to better initiate a deep bond with the mother.
