    A brief tablet-based intervention benefits linguistic and communicative abilities in toddlers and preschoolers
    (2024) Pena, Marcela; Vasquez-Venegas, Constanza; Cortes, Patricia; Pittaluga, Enrica; Herrera, Mitzy; Pino, Esteban J.; Escobar, Raul G.; Dehaene-Lambertz, Ghislaine; Guevara, Pamela
    Young children's linguistic and communicative abilities are foundational for their academic achievement and overall well-being. We present the positive outcomes of a brief tablet-based intervention aimed at teaching toddlers and preschoolers new word-object and letter-sound associations. We conducted two experiments, one involving toddlers ( similar to 24 months old, n = 101) and the other with preschoolers ( similar to 42 months old, n = 152). Using a pre-post equivalent group design, we measured the children's improvements in language and communication skills resulting from the intervention. Our results showed that the intervention benefited toddlers' verbal communication and preschoolers' speech comprehension. Additionally, it encouraged vocalizations in preschoolers and enhanced long-term memory for the associations taught in the study for all participants. In summary, our study demonstrates that the use of a ludic tablet-based intervention for teaching new vocabulary and pre-reading skills can improve young children's linguistic and communicative abilities, which are essential for future development.

    Benefits of home-based administration of palivizumab in high-risk groups
    (2024) Ortiz, Carolina; Vasquez, Ignacia; Zamorano, Alejandra; D'Apremont, Ivonne; Pittaluga, Enrica; Diaz, Marcela; Campos, Catalina
    Palivizumab, a humanized monoclonal antibody against the respiratory syncytial virus (RSV), rrently is indicated in groups at higher risk of developing severe RSV disease, such as extreme premature infants and patients with hemodynamically significant heart disease. In Chile, this strategy guaranteed by Law 20850 (Ricarte Soto Law). Nevertheless, barriers to its administration included the need to transfer these labile patients and exposure to other users, with the risk of contagion waiting rooms. Objective: to describe the impact of the palivizumab administration strategy in home care program for high-risk patients. Patients and Method: retrospective, descriptive, observational cohort study of patients born before 32 weeks of gestation or weighing less than 1500 grams, who received palivizumab between January 2019 and December 2021 at the Hospital Dr. S & oacute;tero Rio. . Results: 272 patients were included (median gestational age: 30 weeks). The percentage of doses administered at home was 35.9% (2019) and 37.2% (2021). Each dose of 2020 following the administration in Neonatology, was administered at home during the COVID-19 pandemic. The median interval between doses was as recommended. Adherence was over 90%. The unadjusted incidence RSV infection was 5.7% (2019), 0% (2020), and 0.9% (2021). Conclusions: palivizumab administration was adequate and timely; home indication was associated with high adherence rates and administration interval between doses in line with current recommendations.

    Language acquisition in premature and full-term infants
    (NATL ACAD SCIENCES, 2010) Pena, Marcela; Pittaluga, Enrica; Mehler, Jacques
    We tested healthy preterm (born near 28 +/- 2 weeks of gestational age) and full-term infants at various different ages. We compared the two populations on the development of a language acquisition landmark, namely, the ability to distinguish the native language from a rhythmically similar one. This ability is attained 4 months after birth in healthy full-term infants. We measured the induced gamma-band power associated with passive listening to (i) the infants' native language (Spanish), (ii) a rhythmically close language (Italian), and (iii) a rhythmically distant language (Japanese) as a marker of gains in language discrimination. Preterm and full-term infants were matched for neural maturation and duration of exposure to broadcast speech. We found that both full-term and preterm infants only display a response to native speech near 6 months after their term age. Neural maturation seems to constrain advances in speech discrimination at early stages of language acquisition.

    OBJECTIVE: To determine whether CS delivery and receipt of antenatal steroids (ANS) in vertex-presenting singletons with a gestational age (GA) between 24 and 30 weeks is associated with improved survival and improved severe intraventricular hemorrhage (sIVH)-free survival.

    Phonological acquisition in preterm infants
    (REVISTA DE NEUROLOGIA, 2010) Pena, Marcela; Pittaluga, Enrica; Farkas, Chamarrita
    Introduction. The stock of phonemes used in the mother tongue is mostly acquired towards the end of the first year of life. Systematic exposure to speech begins, maintains and enhances the learning of native phonemes and lowers sensitivity to non-native ones. Speech deprival gives rise to serious problems in the infant's phonological development, yet little is known about the effects that premature exposure to speech can have on this learning. This study explores this issue by comparing the phonological discrimination of full-term and preterm infants at 12 months of age (corrected age in the preterm infants).
