Important perinatal factors that are associated with early neonatal deaths in very low birth weight preterm infants can be modified by interventions such as improving fetal vitality at birth and reducing the incidence and severity of respiratory distress syndrome. The heterogeneity of early neonatal rates across the different centers studied indicates that best clinical practices should be identified and disseminated throughout the country.

Objetivo: Avaliar os fatores perinatais associados ao óbito neonatal precoce em prematuros com peso ao nascer entre 400 e 1.500 g. Métodos:Coorte prospectiva e multicêntrica dos nascidos vivos com idade gestacional de 23 a 33 semanas e peso de 400-1.500 g, sem malformações em oito maternidades públicas terciárias universitárias entre junho de 2004 e maio de 2005. As características maternas e neonatais e a morbidade nas primeiras 72 horas de vida foram comparadas entre os prematuros que morreram ou sobreviveram até o sexto dia de vida. As variáveis perinatais associadas ao óbito neonatal precoce foram determinadas por regressão logística.Resultados: No período, 579 recém-nascidos preencheram os critérios de inclusão. O óbito precoce ocorreu em 92 (16%) neonatos, variando entre as unidades de 5 a 31%, e tal diferença persistiu controlando-se por um escore de gravidade clínica (SNAPPE-II). A análise multivariada para o desfecho óbito neonatal intra-hospitalar precoce mostrou associação com: idade gestacional de 23-27 semanas (odds ratio -OR = 5,0; IC95% 2,7-9,4), ausência de hipertensão materna (OR = 1,9; IC95% 1,0-3,7), Apgar 0-6 no 5º minuto (OR = 2,8; IC95% 1,4-5,4), presença de síndrome do desconforto respiratório (OR = 3,1; IC95% 1,4-6,6) e centro em que o paciente nasceu.Conclusão: Importantes fatores associados ao óbito neonatal precoce em prematuros de muito baixo peso são passíveis de intervenção, como a melhora da vitalidade fetal ao nascer e a diminuição da incidência e gravidade da síndrome do desconforto respiratório. As diferenças de mortalidade encontradas entre os centros apontam para a necessidade de identificar as melhores práticas e adotá-las de maneira uniforme em nosso meio.

Coagulase-negative staphylococci (CNS) DNAse (15.4%), thermonuclease (7.7%), and enterotoxin A, B or C (37.6%). Taking into consideration that the etiological importance of CNS has often been neglected, the present investigation confirmed that these microorganisms should not be ignored or classified as mere contaminants.

Objective: To verify, in extremely preterm infants, if disagreement between obstetricians and neonatologists regarding proactive management is associated with early death.Study Design: Prospective cohort of 484 infants with 23 0/7 to 26 6/7 weeks, without malformations, born from January 2006 to December 2009 in eight Brazilian hospitals. Pro-active management was defined as indication of X1 dose of antenatal steroid or cesarean section (obstetrician) and resuscitation at birth according to the international guidelines (neonatologist). Main outcome was neonatal death in the first 24 h of life.Result: Obstetricians and neonatologists disagreed in 115 (24%) patients: only neonatologists were proactive in 107 of them. Disagreement between professionals increased 2.39 times the chance of death in the first day (95% confidence interval 1.40 to 4.09), adjusted for center and maternal/ neonatal clinical conditions. Conclusion:In infants with 23 to 26 weeks of gestation, disagreement between obstetricians and neonatologists, translated as lack of antenatal steroids and/or vaginal delivery, despite resuscitation procedures, increases the odds of death in the first day. Keywords: fetal viability; steroids; cesarean section; cardiopulmonary resuscitation; infant newborn; neonatal mortality Introduction According to the International Liaison Group on Resuscitation, in 2010, 1 for neonates at the margins of viability or those with conditions that predict a high risk of mortality or morbidity, attitudes and practice vary according to region and availability of resources. 2 A systematic review 3 shows that at p22 weeks, no scientific society recommends active treatment for the mother to protect the fetus beyond offering compassionate care. A general agreement is also evident for week 25 0/7 to 25 6/7 : antenatal steroid administration are recommended, prenatal transport and Cesarean section are indicated to protect the fetus and resuscitation is offered to all infants without fatal anomalies. However, there exists a gray area for infants between 23 and 24 weeks, which, in some countries, extends through 25 weeks. 3 The active management of gestations at the limit of viability involves three important clinical decisions: the use of antenatal steroids, delivery method and resuscitation at birth. One prospective cohort study between 1993 and 2007 followed 5476 infants with 23 to 29 weeks gestation admitted for neonatal care. The overall mortality among infants exposed to maternal steroids was lower than in infants not exposed: 19% vs 35% at 24 to 29 weeks and 79% vs 89% at 23 weeks. 4 23, 24, 25 and 26 weeks, respectively. 5 In the same study, 8% of the 125 542 live births with 22 to 31 weeks of gestation had Apgar scores <4 at 5 min, which indicates that resuscitation procedures were frequently needed among preterm infants. However, extensive cardiopulmonary resuscitation at birth

LOS incidence and mortality are high in Brazilian VLBW infants. Most risk factors are associated with routine practices at NICU.
