Current situation and new steps in newborn screening in Spain.

After more than 50 years of experience, newborn screening (NBS) programs represent one of the most significant advancements in public health, particularly in pediatric and neonatal care, benefiting almost 350 000 children annually in Spain. Following the inclusion of congenital hearing loss screening in 2003 and screening for seven congenital diseases by newborn blood spot test in 2014 as part of the population-wide neonatal screening program of the National Health System (NHS), significant advances have been achieved in recent years. This progress is evident in the implementation of screening for critical congenital heart diseases, approved in January 2024 by the National Public Health Commission of the Interterritorial Council of the NHS, as well as screening for congenital diseases through the newborn blood spot test, with the incorporation of new conditions enabled by advances in second-tier testing and emerging scientific evidence.

Small for gestational age: concept, diagnosis and neonatal characterization, follow-up and recommendations.

Newborns who do not reach a weight appropriate for their gestational age and sex can be classified in different ways. This article defines the concepts of small for gestational age (SGA) and intrauterine growth restriction, as well as the underlying causes of these conditions, with the goal of establishing consensus definitions for these patients, in whom treatment with growth hormone throughout childhood may be indicated and who may be at risk of developing endocrine or metabolic disorders in puberty and adulthood. Most SGA children experience spontaneous catch-up growth that is usually completed by age 2 years.

Does the use of higher versus lower oxygen concentration improve neurodevelopmental outcomes at 18-24 months in very low birthweight infants?

Background: Immediately after birth, the oxygen saturation is between 30 and 50%, which then increases to 85-95% within the first 10 min. Over the last 10 years, recommendations regarding the ideal level of the initial fraction of inspired oxygen (FiO) for resuscitation in preterm infants have changed from 1.0, to room air to low levels of oxygen (< 0.

Care levels in neonatal units in Spain: an updated vision for a new reality.

The Spanish Society of Neonatology established the care levels of the Neonatal Units in Spain in 2013. Since then, the birth rate in our country, as well as the universalization of knowledge, techniques and patient treatment devices, has evolved significantly. This situation forces a redefinition of the current levels of care based on quality criteria that allow better comparability between the Units and represents a challenge to improve the care of our newborns.

Failure of early non-invasive ventilation in preterm infants with respiratory distress syndrome in current care practice in Spanish level-III neonatal intensive care units - a prospective observational study.

Introduction: Despite advances in respiratory distress syndrome (RDS) management over the past decade, non-invasive ventilation (NIV) failure is frequent and associated with adverse outcomes. There are insufficient data on the failure of different NIV strategies currently used in clinical practice in preterm infants.

Methods: This was a prospective, multicenter, observational study of very preterm infants [gestational age (GA) <32 weeks] admitted to the neonatal intensive care unit for RDS that required NIV from the first 30 min after birth.

Recommendations for transfusion of blood products in neonatology.

The scant evidence on the use of transfusions in neonatal care explains the limitations of current clinical guidelines. Despite this, in this document we explore the most recent evidence to make recommendations for the clinical practice. The prevention of anaemia of prematurity, the use of protocols and restrictive transfusion strategies constitute the best approach for clinicians in this field.

Perinatal palliative care.

Perinatal Palliative Care is a model of care designed to prevent and treat the physical, spiritual, emotional, and social needs of fetuses and newborn infants with life-threatening or life-limiting conditions. The care extends to the infant's family. It is delivered by an interdisciplinary team to improve the quality of life from the time of diagnosis (possibly in utero) into death and bereavement (days, months or years later).

Sedoanalgesia in neonatal units.

Pain recognition and management continues to be a challenge for health professionals in Neonatal Intensive Care Units. Many of the patients are routinely exposed to repeated painful experiences with demonstrated short- and long-term consequences. Preterm babies are a vulnerable high-risk population.

Home births: A growing phenomenon with potential risks.

Home birth is a controversial issue that raises safety concerns for paediatricians and obstetricians. Hospital birth was the cornerstone to reduce maternal and neonatal mortality. This reduction in mortality has resulted in considering pregnancy and childbirth as a safe procedure, which, together with a greater social awareness of the need for the humanisation of these processes, have led to an increase in the demand for home birth.

Recommendations on the skills profile and standards of the neonatal transport system in Spain.

The first hours of life of a sick or premature newborn are crucial for its prognosis and therefore delivery should take place in a center prepared for that degree of complexity. When this condition is not met, the newborn must be transferred in an optimal and safe way to the center that can offer the necessary care. The training, staffing, organization and coordination of the neonatal transport team are essential to guarantee a safe transfer.

Topiramate plus Cooling for Hypoxic-Ischemic Encephalopathy: A Randomized, Controlled, Multicenter, Double-Blinded Trial.

Background And Objectives: Therapeutic interventions to improve the efficacy of whole-body cooling for hypoxic-ischemic encephalopathy (HIE) are desirable. Topiramate has been effective in reducing brain damage in experimental studies. However, in the clinical setting information is limited to a small number of feasibility trials.

Less Invasive Surfactant Administration in Spain: A Survey Regarding Its Practice, the Target Population, and Premedication Use.

Objective: Scientific evidence supports the use of less invasive surfactant administration (LISA) techniques, but certain issues may be limiting its generalized incorporation in clinical practice. The objectives were to determine the level of acceptance of LISA techniques in Spanish hospitals, the types of methods used, the target population, and the premedication administered.

Study Design: An online survey was designed and sent to various secondary/tertiary hospitals in Spain.

Underdosing of Surfactant for Preterm Babies with Respiratory Distress Syndrome in Clinical Practice: A Retrospective Cohort Study.

Objective: To evaluate the initial doses of surfactant administered to preterm infants with respiratory distress syndrome.

Study Design: This is a retrospective cohort study of 206 preterm infants admitted in four level III neonatal intensive care units of acute tertiary care hospitals in Spain between 2013 and 2015.

Results: The mean initial dose of surfactant was 173.

Evolution of Energy Related Metabolites in Plasma from Newborns with Hypoxic-Ischemic Encephalopathy during Hypothermia Treatment.

Therapeutic hypothermia (TH) initiated within 6 h from birth is the most effective therapeutic approach for moderate to severe hypoxic-ischemic encephalopathy (HIE). However, underlying mechanisms and effects on the human metabolism are not yet fully understood. This work aims at studying the evolution of several energy related key metabolites in newborns with HIE undergoing TH employing gas chromatography - mass spectrometry.

Brain Natriuretic Propeptide as an Early Marker of Bronchopulmonary Dysplasia or Death in the Preterm Newborn.

To investigate whether increased brain natriuretic propeptide (NT-proBNP) levels at 48 to 72 h of life are associated with the development of bronchopulmonary dysplasia (BPD) or death in premature neonates. A retrospective study was performed in neonates born before 32 weeks' gestation or with birth weight below 1500 grams, in whom NT-proBNP determination and echocardiography were performed at 48 to 72 h of life. Associations between NT-proBNP levels and the combined outcome BPD or death were analyzed using multivariate logistic regression analysis.

[Oxidative stress in perinatal asphyxia and hypoxic-ischaemic encephalopathy].

Birth asphyxia is one of the principal causes of early neonatal death. In survivors it may evolve to hypoxic-ischaemic encephalopathy and major long-term neurological morbidity. Prolonged and intense asphyxia will lead to energy exhaustion in tissues exclusively dependent on aerobic metabolism, such as the central nervous system.

Primary Cutaneous Aspergillosis in a Preterm Infant.

Primary cutaneous aspergillosis is rare in premature infants. It requires combined medical and surgical strategies. Liposomal amphotericin B is recommended as first-line therapy, but salvage regimens with others antifungal agents, such as voriconazole, have been reported.

[Corrected QT interval during therapeutic hypothermia in hypoxic ischaemic encephalopathy].

Introduction: Therapeutic hypothermia is the standard treatment for hypoxic ischaemic encephalopathy (HIE), despite not knowing all its effects and complications. Sinus bradycardia is one of the consequences of cooling that has been previously documented in the literature, but little is known about the cardiac electrical activity in these patients.

Objective: To determine the corrected QT (QTc) interval in newborns treated with therapeutic hypothermia for HIE.

Brainstem dysgenesis during the neonatal period: diagnosis and management.

Aims: To report our neonatal management experience in patients who received a diagnosis of brainstem dysgenesis (BSD).

Patients And Methods: This study retrospectively reviewed the medical records of 15 neonates with BSD diagnosed between 1984 and 2011. Data on the perinatal period, physical examination, laboratory findings, and management by systems were systematically analyzed.
