(Abstracted from JAMA 2019;321(12):1188–1199) The long-term health outcomes for preterm infants have improved over time, but born at extreme gestational ages continue to present issues of optimal antenatal and postnatal management, resource allocation costs, quality care, outcomes. To better understand variations time trends management extremely birth, study international populations is needed.
BACKGROUND. Knowledge of long-term growth extremely preterm infants in relation to gestational age is incomplete, and there are concerns regarding their poor early childhood. As part a longitudinal study national cohort born at &lt;26 weeks' gestation (extremely immature), development from birth the 11 years was examined, correlates attainment were analyzed. METHODS. Two hundred forty-seven immature children alive April 1990 through March 1992 whole Sweden, 89 (36%) survived. Growth...
In a prospective study, feeding routines of maternity unit and the subsequent patterns 521 newborns were analysed.

Nine percent their mothers' by bottle at least once 21% one or more supplementary feedings with bank. One-quarter children feeds on third day life, indications for this being birth weight less than 3.0 kg, maternal diabetes gestational diabetes, "insufficient amounts"...

A survey to assess the vitamin D nutritional state in 119 pregnant women at term and their newborns was undertaken Riyadh, Saudi Arabia. Concentrations of 25-hydroxy (25-(OH)D) were below 4 ng/ml 30 maternal sera, 11 which they undetectable. The median concentration 25-(OH)D 5.7 ng/ml, is comparable that found Asian vegetarian London. Fifty cord samples had undetectable 25-(OH)D, a total 81 concentrations less than ng/ml. Despite low bloods calcium higher those blood, while serum albumin...

Abstract Aim We evaluated the increased centralisation of extremely preterm (EPT) births in Sweden relation to changes mortality and morbidity. Methods Population‐based data covering Swedish live from 22 + 0 26 6 weeks gestation during 2004–2007 2014–2016 were analysed for associations between time‐period, birth within (inborn) or outside (outborn) regional centres, outcomes.

Abstract Objective Extremes of prepregnancy maternal BMI increase neonatal mortality and morbidity at term. They also the risk extremely preterm (EP, i.e., <27 weeks' gestational age) births. However, association between outcomes for EP babies is poorly understood. Methods We used a cross‐country design, bringing together following three population‐based, prospective, national birth cohorts: EXPRESS (Sweden, 2004–2007); EPICure 2 (UK, 2006); EPIPAGE (France, 2011). included all singleton...
