Single strain versus multispecies probiotic on necrotizing enterocolitis and faecal IgA levels in very low birth weight preterm neonates: A randomized clinical trial.

Background: According to the literature, probiotics are an attractive alternative to prevent necrotizing enterocolitis (NEC). However, due to differences in probiotic composition, randomized controlled trials are necessary to compare different probiotic mixtures. The objective of this study was to compare single strain (Lactobacillus acidophilus boucardii) versus multispecies probiotics on NEC incidence and faecal secretory Immunoglobulin A (sIgA) levels in very low preterm newborns.

Pulse oximetry as a screening test for critical congenital heart disease in term newborns.

Background: Pulse oximetry has been suggested as a screening test for congenital heart disease (CHD) in asymptomatic newborns. However, most newborns in Mexico are discharged from the hospital without this evaluation.

Objective: To evaluate pulse oximetry as a screening test for critical congenital heart disease (CCHD) in term newborns.

Renal function, renal volume, and blood pressure in infants with antecedent of antenatal steroids.

Steroids have been used for more than 20 years in preterm infants to induce pulmonary maturity; however, some long-term effects have been reported, such as insulin resistance and elevation of blood pressure. The aim of our study was to compare renal volume, renal function, and blood pressure in infants between 12-36 months of age with and without antecedent of antenatal steroid treatment. This was a cross-sectional study comprised of three groups of infants (n = 30, respectively): preterm infants with and without antecedent of receiving antenatal steroids, respectively, and full-term infants.
