Reduced pulmonary oxygen diffusion at 36 weeks of postmenstrual age in small-for-gestational-age preterm infants of less than 32 weeks without bronchopulmonary dysplasia.

Background: Small-for-gestational-age (SGA) preterm infants are at increased risk of developing bronchopulmonary dysplasia (BPD). There is limited information on pulmonary oxygen diffusion of SGA preterm infants, particularly in those without BPD.

Objective: To compare the pulmonary oxygen diffusion of SGA to that of appropriate-for-gestational-age (AGA) preterm infants without BPD.

Who Needs a Second Dose of Exogenous Surfactant?

Objective: To identify prenatal and postnatal risk factors associated with surfactant redosing.

Study Design: Retrospective, single-regional center study including all infants born from 24 + 0 to 31 + 6 weeks of gestation in the Marche Region, Italy, and admitted to a single level III regional NICU from January 1, 2004, to February 28, 2021. Clinical factors associated with surfactant redosing were identified through logistic regression analysis.

Oxygen saturation to fraction of inspired oxygen ratio in preterm infants on routine parenteral nutrition with conventional or fish oil containing lipid emulsions.

Introduction: The benefits of intravenous (IV) fish oil (FO), as a source of n-3 long-chain polyunsaturated fatty acids, on lung growth in preterm infants, remain controversial.

Aim: To evaluate if IV FO improves lung growth in small preterm infants on routine parenteral nutrition (PN).

Materials And Methods: We retrospectively reviewed prospectively collected data of preterm infants with a birth weight <1250 g who received routine PN from birth.

Hyperventilation syndrome in adolescents with and without asthma.

Background: Data on the prevalence of hyperventilation syndrome (HVS) in adolescents are scanty.

Objectives: To determine the prevalence of HVS in a population of adolescents with and without asthma, and to verify whether HVS was related to asthma activity.

Methods: A population of adolescents was asked to self-complete a questionnaire, including the Nijmegen questionnaire to assess HVS, and a standardized asthma questionnaire.
