Prediction of neurodevelopment and neuromotor trajectories in very preterm born children up to 11 years of age: PIPARI Study
Very preterm birth is a risk for brain injury and abnormal neurodevelopment. While the incidence of cerebral palsy has decreased due to advances in perinatal and neonatal care, the rate of less severe neuromotor problems continues to be high in very prematurely born children. Neonatal brain imaging can aid in identifying children for closer follow-up and in providing parents information on developmental risks.
This thesis aimed to study the predictive value of structural brain magnetic resonance imaging (MRI) at term age, serial neonatal cranial ultrasound (cUS), and structured neurological examinations during the longitudinal follow-up for the neurodevelopment of very preterm born children up to 11 years of age as a part of the PIPARI Study (The Development and Functioning of Very Low Birth Weight Infants from Infancy to School Age). A further aim was to describe the associations between regional brain volumes and long-term neuromotor profile.
The prospective follow-up comprised of the assessment of neurosensory development at 2 years of corrected age, cognitive development at 5 years of chronological age, and neuromotor development at 11 years of age. Neonatal brain imaging and structured neurological examinations predicted neurodevelopment at all age-points. The combination of neurological examination and brain MRI or cUS improved the predictive value of neonatal brain imaging alone. Decreased brain volumes associated with neuromotor performance. At the age of 11 years, the majority of the very preterm born children had age-appropriate neuromotor development and after-school sporting activities. Long-term clinical follow-up is recommended at least for all very preterm infants with major brain pathologies.Pikkukeskosten neuromotorinen pitkäaikaiskehitys 11 vuoden ikään saakka ja sitä ennustavat tekijät: PIPARI-tutkimus
Pikkukeskosuus on riski aivovauriolle ja poikkeavalle kehitykselle. Vaikka CP-vamman esiintyvyys on alkuvaiheen tehohoidon kehittymisen myötä vähentynyt, lievempiä neuromotorisia ongelmia esiintyy edelleen merkittävästi pikkukeskosina syntyneillä lapsilla. Varhaiset aivojen kuvantamistutkimukset voivat auttaa tunnistamaan pitkäaikaisseurantaa tarvitsevat lapset sekä antamaan vanhemmille tietoa kehitykseen liittyvistä riskeistä.
Tämän väitöskirjatyön tavoitteena oli selvittää lasketun ajan aivojen rakenteellisen magneettitutkimuksen, sarjoittaisen aivojen ultraäänitutkimuksen, ja pitkäaikaisseurannan aikana tehtyjen yksityiskohtaisten neurologisten tutkimusten ennustearvo pikkukeskosten kehitykselle 11 vuoden ikään asti osana PIPARI–tutkimusta (Pienipainoisten riskilasten käyttäytyminen ja toimintakyky imeväisiästä kouluikään). Tavoitteena oli myös kuvailla aivotilavuuksien yhteys neuromotoriseen pitkäaikaiskehitykseen.
Prospektiivinen seuranta sisälsi neurosensorisen kehityksen arvioinnin 2 vuoden korjatussa iässä, kognitiivisen kehityksen arvioinnin 5 vuoden kronologisessa iässä, sekä neuromotorisen kehityksen arvioinnin 11-vuotiaana. Varhaiset aivojen kuvantamistutkimukset sekä yksityiskohtaiset neurologiset tutkimukset ennustivat pikkukeskosten pitkäaikaiskehitystä kaikissa ikäpisteissä. Neurologisten tutkimustulosten yhdistäminen aivojen magneettitutkimuksen tai ultraäänitutkimusten löydöksiin paransi yksittäisen kuvantamistutkimuksen ennustearvoa. Pienemmät aivotilavuudet liittyivät heikompaan neuromotoriseen suoriutumiseen. Suurimmalla osalla pikkukeskosina syntyneistä lapsista oli ikätasoinen neuromotorinen kehitys ja liikuntaharrastus 11-vuotiaana. Pitkäaikaista kliinistä seurantaa suositellaan ainakin kaikille niille pikkukeskosille, joilla on todettu vaikea aivovaurio.Siirretty Doriast
Altered temporal connectivity and reduced meta-state dynamism in adolescents born very preterm
Adolescents born very preterm have an increased risk for anxiety, social difficulties and inattentiveness, i.e. the ‘preterm behavioural phenotype’. The extreme end of these traits comprises the core diagnostic features of attention and hyperactivity disorders and autism spectrum disorder, which have been reported to show aberrant dynamic resting-state functional network connectivity. This study aimed to compare this dynamism between adolescents born very preterm and controls. A resting-state functional magnetic resonance imaging was performed on 24 adolescents born very preterm (gestational agePeer reviewe

Hammersmith Infant Neurological Examination and long-term cognitive outcome in children born very preterm
Aim To study the association between the Hammersmith Infant Neurological Examination (HINE) at age 2 years and neurocognition at age 11 years in children born very preterm. We hypothesized that the HINE at 2 years would be associated with neurocognition, that is, neurological, motor, and cognitive outcomes at 11 years. Method A total of 174 children (mean gestational age 29.0wks, SD 2.7; minimum 23.0, maximum 35.9; 95 [55%] males, 79 [45%] females) born very preterm (birthweight Results The HINE global score was associated with the results of the TINE (odds ratio [OR]=0.9, 95% confidence interval [CI] 0.8-0.9, p=0.001), MABC-2 (beta=1.4, 95% CI 0.7-2.2, p Interpretation A higher HINE global score at 2 years was associated with better general intelligence at 11 years even in children without CP. The HINE may be a useful tool to detect children at risk for later cognitive impairment.Peer reviewe

The HINE may be a useful tool to detect children at risk for later cognitive impairment. What this paper adds A Hammersmith Infant Neurological Examination (HINE) global score at 2 years was associated with long-term neurocognitive function. Severe cognitive impairment was significantly more common in 11-year-old children with complex minor neurological dysfunction compared to typically developing children. The HINE performed at 2 years detects risks of cognitive impairment at 11 years in children born very preterm. A higher HINE score at 2 years was associated with better general intelligence at 11 years.</p
Implementation of neurally adjusted ventilatory assist and high flow nasal cannula in very preterm infants in a tertiary level NICU
Preterm infants treated with invasive ventilation are often affected by bronchopulmonary dysplasia, brain structure alterations, and later neurodevelopmental impairment. We studied the implementation of neurally adjusted ventilatory assist (NAVA) and high flow nasal cannula (HFNC) in a level III neonatal unit, and its effects on pulmonary and central nervous system outcomes. This retrospective cohort study included 193 surviving infants born below 32 weeks of gestation in preimplementation (2007-2008) and postimplementation (2016-2017) periods in a single study center in Finland. The proportion of infants requiring invasive ventilation decreased from 67% in the pre- to 48% in the postimplementation period (p = 0.009). Among infants treated with invasive ventilation, 68% were treated with NAVA after its implementation. At the same time, the duration of invasive ventilation of infants born at or below 28 weeks increased threefold compared with the preimplementation period (p = 0.042). The postimplementation period was characterized by a gradual replacement of nasal continuous positive airway pressure (nCPAP) with HFNC, earlier discontinuation of nCPAP, but a longer duration of positive pressure support. The proportion of normal magnetic resonance imaging (MRI) findings at term corrected age increased from 62% to 84% (p = 0.018). Cognitive outcome improved by one standard score between the study periods (p = 0.019). NAVA was used as the primary mode of ventilation in the postimplementation period. During this period, invasive ventilation time was significantly prolonged. HFNC led to a decrease in the use of nCPAP. The change in the respiratory support might have contributed to the improvement in brain MRI findings and cognitive outcomes
Fewer maternal depression symptoms after the Close Collaboration with Parents intervention : Two-year follow-up
Aim
To test whether the implementation of the Close Collaboration with Parents intervention at a neonatal intensive care unit (NICU) decreases depression symptoms of mothers up to two years after the delivery of preterm infants.
Methods
We used a non-equivalent two-group design, comparing mothers of very low birthweight infants in the same NICU before (2001–2006) and after (2011–215) the intervention. The unit carried out the educational intervention (2009–2012) that was targeted at its healthcare team and aimed to improve their skills to collaborate with parents. Maternal depression symptoms were measured using the Edinburgh Postnatal Depression Scale (EPDS) six months and two years after the expected birth date of the infant.
Results
We found a median difference of 2.56 (95% CI from 1.64 to 3.48) in EPDS at the two-year follow-up between the pre-intervention and post-intervention groups, p < 0.001. Furthermore, we found no interaction between measurement time-points and group, implying that the intervention effect on maternal depression symptoms was similar at the six-month and two-year time-points.
Conclusion
The intervention seems to have long-term preventive effects on maternal depressive symptoms. This effect is of clinical significance as prolonged maternal depression associates with adverse child outcomes.© 2022 The Authors.
