Reference Ranges for Regional Cerebral Oxygen Saturation with Masimo O3 after Birth and Differences with Other Devices.

Objective:  Cerebral oximetry using near-infrared spectroscopy (NIRS) is a noninvasive optical technology widely used in neonatology. The present study aimed to define reference ranges for cerebral tissue oxygen saturation (crSO) with a new four-wavelength NIRS device, Masimo O3 oximeter, during immediate transition after birth and compare values with those obtained previously with NIRO 200NX.

Study Design:  This was a prospective observational study using Masimo O3 device to measure crSO and regional cerebral fractional tissue oxygen extraction (cFTOE) in healthy term newborns delivered by primary cesarean section, during the 15 minutes after cord clamping.

Parasympathetic evaluation for procedural pain assessment in neonatology.

Introduction: The Newborn Infant Parasympathetic Evaluation (NIPE) index is an instrument that enables continuous, fast and objective assessment of neonatal discomfort. The aim of the study was to analyse changes in NIPE values after performance of blood draws and the factors involved in this variation.

Material And Methods: We conducted a prospective observational study.

Developmental dysplasia of the hip: Beyond the screening. Physical exam is our pending subject.

Introduction: Developmental dysplasia of the hip is a common cause of disability among children. Early detection leads to better prognosis. There are some risk factors that increase the possibility of developing a dysplasia.

Baby Friendly Hospital Initiative Breastfeeding Outcomes in Mothers with COVID-19 Infection During the First Weeks of the Pandemic in Spain.

Background: Adherence to the Ten Steps of the Baby-Friendly Hospital Initiative has been shown to have a protective role for the initiation and maintenance of breastfeeding.

Research Aims: (1) To determine the breastfeeding rate during the first 6 months of life in children of mothers diagnosed with COVID-19 infection at the time of birth; and (2) to assess the possible influence of being born in a center with Baby-Friendly Hospital Initiative accreditation.

Methods: This was a two-group comparative longitudinal observational study of infants born to mothers with COVID-19 at the time of birth, between March 13-May 31, 2020 (the first wave of the pandemic) in Spain.

[Develomental dysplasia of the hip: beyond the screening. Physical exam is our pending subject].

Introduction: Developmental dysplasia of the hip is a common cause of disability among children. Early detection leads to better prognosis. There are some risk factors that increase the possibility of developing a dysplasia.

Maternal, Perinatal and Neonatal Outcomes With COVID-19: A Multicenter Study of 242 Pregnancies and Their 248 Infant Newborns During Their First Month of Life.

Background: Our aim was to describe the clinical features of mothers with coronavirus disease 2019 (COVID-19) infection during gestation or delivery, and the potential vertical transmission. We also wish to evaluate the possible horizontal transmission after hospital discharge, by means of a follow-up of all the newborns included at 1 month of age.

Methods: This multicenter descriptive study involved 16 Spanish hospitals.

[External influences on birth deliveries: Lunar gravitational and meteorological effects].

Objective: To investigate the influence of external factors such as lunar and meteorological effects on the frequency of birth deliveries. It includes the lunar gravitational force using the scarcely investigated lunar apogee and perigee (furthest and closest distance to earth, respectively).

Material And Methods: A retrospective study was conducted by reviewing the medical records of all spontaneous single deliveries during a 4 year period (2015-2018).

Bioelectrical impedance vector values in a Spanish healthy newborn population for nutritional assessment.

Introduction: Vector bioimpedance analysis (BIVA) can be very useful for the evaluation of body composition, hydration, and nutritional status in infants and newborns. The objective of this study was to determine the impedance vector distribution for a group of healthy newborn Spanish children.

Methods: This was a cross-sectional, descriptive study conducted with 154 healthy, Spanish newborns (gestational age: 37-41 weeks) aged 24 to 72 hours (79 males, 75 females).

[Clinical observation of newborns with infection risk: A safe practice].

Introduction: Early-onset neonatal sepsis refers to an infection which starts during the first 72hours of birth, and can lead to significant morbidity and mortality. Scientific evidence shows that infected infants present with symptoms during the first hours after delivery. There has been a significant decrease in this condition with the implementation of guidelines for its prevention.

Pain and stress assessment after retinopathy of prematurity screening examination: indirect ophthalmoscopy versus digital retinal imaging.

Background: Increasingly, neonatal clinics seek to minimize painful experiences and stress for premature infants. Fundoscopy performed with a binocular indirect ophthalmoscope is the reference examination technique for screening of retinopathy of prematurity (ROP), and it is associated with pain and stress. Wide-field digital retinal imaging is a recent technique that should be evaluated for minimizing infant pain and stress.
