1. Ventilation-induced changes correlate to pulmonary vascular response and VEGF, VEGFR-1/2, and eNOS expression in the rat model of postnatal hypoxia
Neonatal asphyxia occurs due to reduction in oxygen supply to vital organs in the newborn. Rapid restoration of oxygen to the lungs after a long period of asphyxia can cause lung injury and decline of respiratory function, which result from the activity of molecules that induce vascular changes in the lung such as nitric oxide (NO) and vascular endothelial g

2. Factors associated with the need for ventilation at birth of neonates weighing ≥2,500 g
OBJECTIVES: Approximately 20-40% of annual global neonatal deaths occur among infants with birthweights ≥2,500 g, and most of these deaths are associated with intrapartum asphyxia in low- and middle-income countries. This study aims to evaluate the peripartum variables associated with the need for resuscitation at birth of neonates weighing ≥2,500 g. M

3. Brain caspase-3 and intestinal FABP responses in preterm and term rats submitted to birth asphyxia
Neonatal asphyxia can cause irreversible injury of multiple organs resulting in hypoxic-ischemic encephalopathy and necrotizing enterocolitis (NEC). This injury is dependent on time, severity, and gestational age, once the preterm babies need ventilator support. Our aim was to assess the different brain and intestinal effects of ischemia and reperfusion in n

4. Marcadores prognósticos de evolução neonatal de recém-nascidos de termo portadores de asfixia perinatal / Prognostic markers of neonatal outcome newborn term patients with perinatal asphyxia
A asfixia perinatal e sua mais grave complicação, a encefalopatia hipóxicoisquêmica (EHI) são causas de elevada mortalidade e de sequelas neurológicas no recém-nascido (RN). Evidencias de comprometimento cerebral podem ser detectadas logo na primeira semana de vida e o diagnóstico precoce é de grande importância para o tratamento e seguimento. OBJE

5. Hypoxia/reoxygenation-induced myocardial lesions in newborn piglets are related to interindividual variability and not to oxygen concentration
OBJECTIVE: Evaluation of myocardial histological changes in an experimental animal model of neonatal hypoxiareoxygenation. METHODS: Normocapnic hypoxia was induced in 40 male Landrace/Large White piglets. Reoxygenation was initiated when the animals developed bradycardia (HR <60 beats/min) or severe hypotension (MAP <15 mmHg). The animals were divided into f

6. Epidemiologia dos óbitos neonatais hospitalares associados à asfixia perinatal em Maceió, Alagoas, 2009 / Epidemiology of hospital neonatal deaths associated with perinatal asphyxia in Maceió, Alagoas, 2009.
Introdução: Alagoas é a Unidade Federativa com maior taxa de mortalidade infantil e neonatal no Brasil, sendo impreterível conhecer seus determinantes na capital. Objetivo: Descrever a epidemiologia dos óbitos neonatais hospitalares associados à asfixia ao nascer, além da infra-estrutura para o atendimento neonatal, em Maceió, no ano de 2009. Método

Objective: To describe epidemiologic frequency and characteristics of intra-hospital neonatal deaths associated to perinatal asphyxia in the country side of Alagoas state in 2009. Method: Prospective cross-seccional study with weekly active search for medical records of mothers and their newborn infants who died before 28 days of age from January 1st to Dece

8. S100B protein related neonatal hypoxia / Relação da proteína S100B com a hipóxia neonatal
A participação de marcadores bioquímicos na avaliação de quadros de asfixia neonatal é cada vez mais relevante. A proteína S100B é de particular importância neste campo. O objetivo deste estudo foi procurar destacar a importância da proteína S100B na avaliação de recém-nascidos a termo com quadro de encefalopatia hipóxico-isquêmica, assim com

9. Inhibition of in vitro CO2 production and lipid synthesis by 2-hydroxybutyric acid in rat brain
2-Hydroxybutyric acid appears at high concentrations in situations related to deficient energy metabolism (e.g., birth asphyxia) and also in inherited metabolic diseases affecting the central nervous system during neonatal development, such as "cerebral" lactic acidosis, glutaric aciduria type II, dihydrolipoyl dehydrogenase (E3) deficiency, and propionic ac

10. LesÃes de pele em recÃm-nascidos na unidade de terapia intensiva neonatal / Skin wounds in newborns hopitalized in neonatal intensive care unite
Infants in the Neonatal Intensive Care Unit (NICU) often get skin lesions on account of the many stressful procedures they are exposed to. This prospective, quantitative and descriptive study was carried out at a public health facility in Fortaleza (Northeastern Brazil) from March to May 2007, in order to investigate skin lesion patterns in infants in the NI

11. The oral motor capacity and feeding performance of preterm newborns at the time of transition to oral feeding
The objective of the present study was to determine the oral motor capacity and the feeding performance of preterm newborn infants when they were permitted to start oral feeding. This was an observational and prospective study conducted on 43 preterm newborns admitted to the Neonatal Intensive Care Unit of UFSM, RS, Brazil. Exclusion criteria were the presen

12. Prevalence of perinatal asphyxia and hypoxic-ischemic encephalopathy in term newborns considering two diagnostic criteria and the type of obstetric assistance / Prevalência de asfixia perinatal e encefalopatia hipóxico-isquêmica em recém-nascidos de termo considerando dois critérios diagnósticos e o tipo de assistência obstétrica
INTRODUÇÃO: A asfixia perinatal é uma das principais causa de óbito nos recémnascidos (RN) de termo acima de 2500g no Brasil, sendo também a causa mais importante de encefalopatia e lesão cerebral permanente em crianças. Não existindo ainda um consenso acerca de qual seria o melhor critério para seu diagnóstico. OBJETIVOS: Verificar a prevalência
