Music and reading activities in early childhood associated with improved language development in preterm infants at 2-3 years of age.

Introduction: Children born preterm are at increased risk for adverse neurodevelopmental outcomes. Music and reading activities in childhood could ameliorate these difficulties, as they have shown benefits on both neural and behavioral levels. However, only a few studies have assessed these potential benefits in preterm-born children.

No impact of parental singing during the neonatal period on cognition in preterm-born children at 2-3 years.

Aim: Studies examining the long-term effects of neonatal music interventions on the cognition of children born preterm are scarce. We investigated whether a parental singing intervention before term age improves cognitive and language skills in preterm-born children.

Methods: In this longitudinal, two-country Singing Kangaroo, randomised controlled trial, 74 preterm infants were allocated to a singing intervention or control group.

Latent class growth analysis identified different trajectories in cognitive development of extremely low birthweight children.

Background: Recent longitudinal studies suggest stable cognitive development in preterm children, although with great individual variation. This prospective neurocognitive follow-up study of extremely low birthweight (ELBW, <1000 g) children aimed to characterise groups with different developmental trajectories from preschool to preteen age.

Methods: ELBW children (n=115) born in Finland in 1996-1997 participated in cognitive assessments at a median age of 5.

Repeated Parental Singing During Kangaroo Care Improved Neural Processing of Speech Sound Changes in Preterm Infants at Term Age.

Preterm birth carries a risk for adverse neurodevelopment. Cognitive dysfunctions, such as language disorders may manifest as atypical sound discrimination already in early infancy. As infant-directed singing has been shown to enhance language acquisition in infants, we examined whether parental singing during skin-to-skin care (kangaroo care) improves speech sound discrimination in preterm infants.

Neural processing of changes in phonetic and emotional speech sounds and tones in preterm infants at term age.

Objective: Auditory change-detection responses provide information on sound discrimination and memory skills in infants. We examined both the automatic change-detection process and the processing of emotional information content in speech in preterm infants in comparison to full-term infants at term age.

Methods: Preterm (n = 21) and full-term infants' (n = 20) event-related potentials (ERP) were recorded at term age.

An extensive pattern of atypical neural speech-sound discrimination in newborns at risk of dyslexia.

Objective: Identifying early signs of developmental dyslexia, associated with deficient speech-sound processing, is paramount to establish early interventions. We aimed to find early speech-sound processing deficiencies in dyslexia, expecting diminished and atypically lateralized event-related potentials (ERP) and mismatch responses (MMR) in newborns at dyslexia risk.

Methods: ERPs were recorded to a pseudoword and its variants (vowel-duration, vowel-identity, and syllable-frequency changes) from 88 newborns at high or no familial risk.

Caffeine and supplemental oxygen effectively suppress periodic breathing with only minor effects during long episodes of apnoea in preterm infants.

Aim: We investigated the characteristics and effects of sleep stage, supplemental oxygen and caffeine on periodic breathing (PB) and apnoea of prematurity (AOP) in preterm infants.

Methods: This 2013-2015 study recruited 21 preterm infants on neonatal wards in the Helsinki and Uusimaa Hospital District, Finland, at a median corrected gestational age of 35.7 weeks and performed polysomnography at baseline, during supplemental oxygen and during caffeine treatment.

Behavioral and evoked potential measures of distraction in 5-year-old children born preterm.

Executive and attention dysfunctions are common in very preterm children. We studied their involuntary attention process by using behavioral measurements and auditory event-related potentials (AERP) with a distraction paradigm at age five years. The active task was to distinguish between two animal sounds.

[From preterm birth to adulthood].

Mortality among low birthweight infants has decreased and their neurological prognosis has improved over the recent decades. A major neurological impairment is, however, still found at preschool age in almost one fifth of those born with a birthweight of less than 1000 g. They often have difficulties in scholastic skills and become independent more slowly than their age-mates, but most of them will lead a normal adult life.

Neurocognitive test profiles of extremely low birth weight five-year-old children differ according to neuromotor status.

The neurocognitive outcome of children born with extremely low birth weight (ELBW) is highly variable due to the complexity of morbidity. So far, no study has compared comprehensive neuropsychological test profiles in groups with different neuromotor status. In a national cohort of ELBW children neuropsychological test profiles were assessed in 4 groups defined according to a neurological examination at 5 years of age: normal neuromotor status (N = 56), motor coordination problems (N = 32), multiple subtle neuromotor signs including both motor coordination problems and deviant reflexes (N = 20), and spastic diplegia (N = 12).

Fetal growth restriction in preterm infants and cardiovascular function at five years of age.

Objectives: We have previously reported an increased cardiac workload in newborn preterm small (SGA) infants, but not in infants appropriate for gestational age (AGA). We hypothesized that these cardiovascular changes will persist at follow-up at 5 years of age.

Study Design: We assessed blood pressure, echocardiography, and skin perfusion with laser Doppler flowmetry in 22 SGA (821 +/- 248 g, 28.

Auditory event-related potentials and cognitive function of preterm children at five years of age.

Objective: In our previous study, auditory event-related potentials (AERPs) in preterm 1-year-old children had a positive deflection at 150-350 ms that correlated positively with their 2-year neurodevelopmental outcome. In a study of the same subjects at age 5, our aim was to assess AERPs and their relationship to neuropsychological test results.

Methods: Preterm small (SGA, n=13), appropriate for gestational age (AGA, n=15), and control (n=13) children were assessed with an Easy paradigm presenting a large frequency change accompanied with occasional novel sounds, and a Challenging paradigm presenting small frequency and duration changes with a rapid rate.

Neurodevelopmental outcome at 5 years of age of a national cohort of extremely low birth weight infants who were born in 1996-1997.

Objective: Increasing survival of extremely low birth weight (ELBW; birth weight < 1000 g) infants raises a concern regarding the risks of adverse long-term outcome such as cognitive dysfunction. Few studies have reported long-term follow-up of representative regional cohorts. The objective of this study was to assess the 5-year outcome of a prospectively followed national ELBW infant cohort.

Atypical auditory event-related potentials in preterm infants during the first year of life: a possible sign of cognitive dysfunction?

We assessed auditory event-related potentials in small-for-gestational-age (SGA; 850 +/- 258 g, 28.9 +/- 3.3 gestational wk; n = 15) and appropriate for gestational age (AGA; 1014 +/- 231 g, 26.
