Inquiring about the MHGD on LBW term babies could be useful in the inference of IUGR, although we need other tools so that altogether can help to predict possible complications and to plan preventive actions.
Maternal prenatal history and neonatal risk complications for low-weight for gestational age term newborns

Background: Low-birth-weight (LBW < 2.5 kg or < 10 percentile) could be caused by constitutional matters (small for gestational age) or by intrauterine growth restriction (IUGR), both with different neonatal complications. Without an adequate prenatal evaluation, it is hard to establish those conditions. Knowing the maternal history for gestational diseases (MHGD), such as hypertension, hypothyroidism (HT) or diabetes, and among others, could help clarify that difference. This work aimed to determine if having MHGD is associated with neonatal complications in newborns with LWB. Methods: Retrospective cohort study, which included 349 with LWB at term (e 37 WG) grouped into those with or without MHGD at a hospital nursery. The frequency of respiratory distress (RD), hypoglycemia (HG), and hyperbilirubinemia (HBr) was determined. Results: Nearly 16.6% (58/349) had MHGD (58.6% for HBP and 41.3% for HT alone or combined). The neonate with MHGD was more borderline term (37 WGA, 55.2% vs. 35.1%, p = 0.037), and had lower weight (difference near 100 g; p = 0.028), had more cases with HG (13.6%; CI 95% -4.08-31.2%) but developed less RD (difference of -4.7%; CI 95%: -20.6-11.05%). HG in 39 WGA was only seen among neonates without MHGD (difference 12.7%; CI 95% = 3.9-31.5%) just as for the HBr cases (three). conclusions: Inquiring about the MHGD on low-birth-weight term babies could be useful in the inference of IUGR, although we need other tools so that altogether can help to predict complications and to plan preventive actions.
Niveles normales del marcador lipocalina asociada con gelatinasa de neutrófilo (NGAL) en orina en recién nacidos pretérmino y de término a las 24 y 72 horas de vida

Introduccin: El biomarcador lipocalina asociada a gelatinasa de neutrfilo (NGAL) en orina presenta alta excrecin en caso de isquemia de clulas renales del asa de Henle y tbulo colector; hasta ahora los valores normales en neonatos son controversiales. Objetivos: Presentar los valores de NGAL urinarios en neonatos sanos a las 24 y 72 horas de vida, segn grupos de semanas de edad gestacional (SEG). Material y mtodos: 70 neonatos (25-32 SEG, n = 25; 33-35 SEG, n = 25; 36-38 SEG, n = 10; 39-41 SEG, n=10). Los niveles de NGAL (ng/mL) urinarios se determinaron por quimioluminiscencia. Los valores se muestran como mediana y valores mnimo y mximo (mediana [min -max]). Resultados: Los niveles de NGAL fueron diferentes segn grupos de edad gestacional, tanto a las 24 horas como a las 72 horas. A las 24 horas = 25-32 SEG = 18.2 [0.5-543.1], 33-35 SEG = 22.3 [0.9-84.4], 36-38 SEG = 10.1 [2.5-181.9], 39-41 SEG = 20.4 [0-577]; a las 72 horas = 25-32 SEG = 47.2 [7.5-441.2], 33-35 SEG = 33.0 [4.7-235.5], 36-38 SEG = 27.7 [4.09-173.1] 39-41 SEG = 17.8 [2.0-113.5]. Conclusin: Los valores de NGAL urinarios normales en
