Thrombin, protein C, and protein S values in mother-infant dyads in the postpartum period.

Introduction: The objective of the study was to establish the normal range for the levels of antithrombin (AT), protein C (PC), and protein S (PS) in the first week post birth in mother-infant pairings, adjusting for obstetric and perinatal factors, based on 2 different laboratory methods.

Methods: Determinations were carried out in 83 healthy term neonates and their mothers, establishing 3 postpartum age groups: 1-2 days, 3 days, and 4-7 days.

Results: There were no differences in the levels of any of the proteins between the different age groups in neonates or mothers in the first week post birth.

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.

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).

Mother's Bed Incline and Desaturation Episodes in Healthy Term Newborns during Early Skin-to-Skin Contact: A Multicenter Randomized Controlled Trial.

Introduction: Early skin-to-skin contact (ESSC) is associated with rare, sudden, unexpected postnatal collapse episodes. Placing the newborn in ESSC closer to an upright position may reduce the risk of airway obstruction and improve respiratory mechanics. This study assessed whether a greater inclination of the mother's bed during ESSC would reduce the proportion of healthy term newborns (HTNs) who experienced episodes of pulse oximeter saturation (SpO2) <91%.

Development, Reliability, and Testing of a New Rating Scale for Neonatal Encephalopathy.

Objective: To develop and test the Neonatal Encephalopathy-Rating Scale (NE-RS), a new rating scale to grade the severity of neonatal encephalopathy (NE) within the first 6 hours after birth.

Study Design: A 3-phase process was conducted: (1) design of a comprehensive scale that would be specific, sensitive, brief, and unsophisticated; (2) evaluation in a cohort of infants with neonatal encephalopathy and healthy controls; and (3) validation with brain magnetic resonance imaging findings and outcome at 2 years of age.

Results: We evaluated the NE-RS in 54 infants with NE and 28 healthy infants.

Associations between neural injury markers of intrauterine growth-restricted infants and neurodevelopment at 2 years of age.

The aim of this study was to evaluate the relationships between brain injury biomarkers in intrauterine growth-restricted (IUGR) infants (S100B and neuron-specific enolase (NSE)) and neurodevelopment at 2 years of age. This prospective case-control study was a cooperative effort among Spanish Maternal and Child Health Network (Retic SAMID) hospitals. At inclusion, biometry for estimated fetal weight and feto-placental Doppler variables were measured for each infant.

Neonatal Arterial Ischemic Stroke: Risk Related to Family History, Maternal Diseases, and Genetic Thrombophilia.

The objective of this study was to evaluate the heritability of neonatal arterial ischemic stroke (NAIS) in relation to family history of thromboembolic event, maternal diseases, and thrombophilia in both parents ( F5G1691A, F2G20210A, and MTHFRC677 T mutations). Forty-two consecutive infants ≥36 weeks of gestation <28 days of life with acute symptomatic NAIS and their parents, as well as 129 controls, were prospectively recruited. Information on maternal data (age, body mass index, oral contraception, migraine, epilepsy, hypertension, and immune disease) and a 3-generation pedigree regarding myocardial infarction, pulmonary embolism, cerebrovascular event, and deep vein thrombosis were obtained.

The Severity of Hypoxic-Ischemic Encephalopathy Correlates With Multiple Organ Dysfunction in the Hypothermia Era.

Objectives: The objectives are to 1) determine whether there is a positive correlation between the severity of hypoxic-ischemic encephalopathy and multiple organ dysfunction and 2) evaluate the organ dysfunction pattern in infants with hypoxic-ischemic encephalopathy in the hypothermia era.

Design: Retrospective observational study of prospective data collected between April 2009 and December 2012.

Setting: The study took place in the neonatal ICU of Hospital Sant Joan de Déu-Hospital Clínic of Barcelona.

The model of Palliative Care in the perinatal setting: a review of the literature.

Background: The notion of Palliative Care (PC) in neonatal and perinatal medicine has largely developed in recent decades. Our aim was to systematically review the literature on this topic, summarise the evolution of care and, based on the available data, suggest a current standard for this type of care.

Methods: Data sources included Medline, the Cochrane Library, CINAHL, and the bibliographies of the papers retrieved.

Abundance of circulating preadipocyte factor 1 in early life.

Objective: Soluble preadipocyte factor 1 (Pref-1) inhibits adipocyte differentiation. We tested whether circulating levels of soluble Pref-1 are higher in smaller fetuses.

Research Design And Methods: We performed longitudinal assessments of circulating Pref-1 in infants born appropriate for gestational age (AGA) or small for gestational age (SGA) and also in late-gestational women and in newborns on days 2 and 3.

Immunogenicity and reactogenicity of a booster dose of a novel combined Haemophilus influenzae type b-Neisseria meningitidis serogroup C-tetanus toxoid conjugate vaccine given to toddlers of 13-14 months of age with antibody persistence up to 31 months of age.

Background: A combined Haemophilus influenzae type b and Neisseria meningitidis serogroup C tetanus toxoid conjugate vaccine (Hib-MenC-TT) may be a convenient alternative to separate Hib and MenC conjugate vaccines.

Methods: Healthy infants randomized in a previous study for priming at 2, 4, and 6 months: Hib-MenC-TT primed group, 3 doses of Hib-MenC-TT + DTPa-HBV-IPV (N = 87); MenC-TT primed group, 2 doses of MenC-TT (NeisVac-C; Baxter Healthcare SA, Zuürich, Switzerland) + 3 doses of DTPa/Hib containing vaccines (N = 178); MenC-CRM primed group, 3 doses of MenC-CRM197(Meningitec; Wyeth Corporation Delaware, Madison, NJ) + DTPa-HBV-IPV/Hib (N = 93). At 13-14 months of age, Hib-MenC-TT and MenC-TT primed groups received a Hib-MenC-TT booster dose and the MenC-CRM primed group a booster dose of DTPa-HBV-IPV/Hib.

[Reduced postnatal growth in very low birth weight newborns with GE < or = 32 weeks in Spain].

Aim: To analyze postnatal growth restriction in a cohort of very low birth weight (VLBW) infants with gestational age < or = 32 weeks in 55 Spanish neonatal units (SEN 1500 Network) during 2002 and 2003.

Methods: Weight, length and head circumference were recorded at birth, and at discharge. Weight was also recorded at 28 days postnatal, and 36 weeks of postmenstrual age.

Immunogenicity and reactogenicity of primary immunization with a novel combined Haemophilus influenzae Type b and Neisseria meningitidis Serogroup C-tetanus toxoid conjugate vaccine coadministered with a Diphtheria-tetanus-acellular Pertussis-hepatitis B-inactivated poliovirus vaccine at 2, 4 and 6 months.

Background: This phase II study evaluated the immunogenicity and reactogenicity of primary vaccination with a novel Hib-MenC conjugate vaccine (GlaxoSmithKline [GSK] Biologicals) coadministered with DTPa-HBV-IPV (GSK Biologicals) at 2, 4 and 6 months.

Methods: Healthy infants were randomized to receive Hib-MenC coadministered with DTPa-HBV-IPV (N = 117) or MenC-CRM (Wyeth) coadministered with DTPa-HBV-IPV/Hib (GSK Biologicals; N = 120) at 2, 4 and 6 months. Antibody concentrations were measured before vaccination and after doses 2 and 3.

Immunogenicity and reactogenicity of primary immunization with a hexavalent diphtheria-tetanus-acellular pertussis-hepatitis B-inactivated polio-Haemophilus influenzae type B vaccine coadministered with two doses of a meningococcal C-tetanus toxoid conjugate vaccine.

Background: This study evaluated the concurrent use of meningococcal C tetanus conjugate (MenC-TT) vaccine (NeisVac-C) with DTaP-based combinations, according to 2 vaccination schedules, one of which included hepatitis B vaccination at birth (Trial DTaP-HBV-IPV/Hib-097).

Methods: Healthy infants were randomized to receive either DTaP-HBV-IPV/Hib (Infanrix hexa) at 2, 4, and 6 months (N = 115) or HBV at birth followed by DTaP-HBV-IPV/Hib at 2 and 6 months and DTaP-IPV/Hib (Infanrix-IPV Hib) at 4 months (N = 115). In both groups 2 doses of MenC-TT conjugate were coadministered at 2 and 4 months, and compared with 3 doses of MenC-CRM197 conjugate (Meningitec) coadministered at 2, 4, and 6 months with DTaP-HBV-IPV/Hib (N = 120).

Beta2-microglobulin concentrations in cerebrospinal fluid correlate with neuroimaging findings in newborns with symptomatic congenital cytomegalovirus infection.

Overview: In newborns with symptomatic congenital cytomegalovirus (CMV) infection, neuroimaging is the best available predictor of neurodevelopmental outcome. Cerebrospinal fluid (CSF) findings in congenital CMV infection have seldom been described. Neonates with central nervous system infections present high CSF Beta(2)-microglobulin (beta(2)-m) levels.

Cerebrospinal fluid leucocyte counts in healthy neonates.

Objectives: To determine the cerebrospinal fluid (CSF) white blood cell (WBC) count of normal term neonates, and compare the CSF WBC profile of normal and symptomatic infants without infection of the central nervous system (CNS).

Method: Neonates were included if (a) they were at risk of congenital Toxoplasma infection and had undergone a lumbar puncture to assess CNS involvement, and (b) serial specific serum IgG and IgM determinations had ruled out congenital infection. According to neonatal chart reviews, 30 consecutive patients without CNS infection were classified as normal (absolutely asymptomatic) or symptomatic (any kind of symptoms).

[Clinical progress of neonatal non-ketotic hyperglycinemia under treatment].

Introduction: Non-ketotic hyperglycinemia is a congenital error in the breakdown of glycine. The most common type is the classical neonatal form, which begins at the age of a few days with symptoms of lethargy, hypotonia, myoclonia, convulsions, apneas and, frequently, ends in death. Survivors usually develop intractable epilepsy and mental retardation.

Implications of postvaccination hepatitis B surface antigenemia in the management of exposures to body fluids.

A neonate vaccinated against HBV was the source of an occupational exposure to blood. She was tested for hepatitis B surface antigen and found to be positive, leading to unnecessary treatment, retesting, and concern. Evaluation of the infectious status of HBV should rely on other means if vaccination has recently occurred.
