Usefulness of ICF-CY to define functioning and disability in very low birth weight children: a retrospective study

Robot-assisted rehabilitation for children with neurological disabilities: Results of the Italian consensus conference CICERONE

BACKGROUND

The use of robotic technologies in pediatric rehabilitation has seen a large increase, but with a lack of a comprehensive framework about their effectiveness.

OBJECTIVE

An Italian Consensus Conference has been promoted to develop recommendations on these technologies: definitions and classification criteria of devices, indications and limits of their use in neurological diseases, theoretical models, ethical and legal implications. In this paper, we present the results for the pediatric age.

METHODS

A systematic search on Cochrane Library, PEDro and PubMed was performed. Papers published up to March 1st, 2020, in English, were included and analyzed using the methodology of the Centre for Evidence-Based Medicine in Oxford, AMSTAR2 and PEDro scales for systematic reviews and RCT, respectively.

RESULTS

Some positives aspects emerged in the area of gait: an increased number of children reaching the stance, an improvement in walking distance, speed and endurance. Critical aspects include the heterogeneity of the studied cases, measurements and training protocols.

CONCLUSION

Many studies demonstrate the benefits of robotic training in developmental age. However, it is necessary to increase the number of trials to achieve greater homogeneity between protocols and to confirm the effectiveness of pediatric robotic rehabilitation.

Development of a new scoring method in the neurofunctional assessment of preterm infants

Infants born preterm are at high risk of presenting neurodevelopmental delay. The Neurofunctional Assessment (NFA) describes infants' neurodevelopment through the evaluation of six different domains. This study aimed to evaluate how, in a cohort of preterm infants, each NFA domain assessed at 3 months of corrected age (CA) was associated with neurodevelopment at 2 years of CA using the Griffiths Mental Developmental Scales Extended Revised (GMDS-ER). In addition, by introducing the NFA complexity score (CS), the study aimed to define a threshold that can help clinicians discriminate infants at higher risk of later neurodevelopmental delay. We conducted an observational, longitudinal study including 211 preterm infants. At 3 months of CA, infants who had normal scores in each domain showed a significantly higher GMDS-ER global quotient (GQ) at 2 years of CA. In addition, linear model results showed a significant negative relationship between the NFA CS and 2-year GMDS-ER GQ (estimate: - 0.27; 95% CI - 0.35, - 0.20; p value < 0.001). Each 10-point increase in the NFA CS was associated with an average 2.7-point decrease in the GMDS GQ. These results highlight how the NFA domains and NFA CS are compelling instruments for the early identification of children at risk for long-term adverse outcomes.

Neuroprem 2: An Italian Study of Neurodevelopmental Outcomes of Very Low Birth Weight Infants

Background: Despite the increased survival of preterm newborns worldwide, the risk of neurodevelopmental disabilities remains high. Analyzing the outcomes of the preterm population can identify risk factors and enable specific early interventions. Aims: Neuroprem is a prospective cohort study of very low birth weight (VLBW) infants that aims to evaluate the neurodevelopmental outcomes and risk factors for severe functional disability at 2 years of corrected age. Methods: Nine Italian neonatal intensive care units participated in the network. The Griffiths Mental Developmental Scales (GMDS-R) or the Bayley Scales of Infant and Toddler Development (BSDI III) and a neuro-functional evaluation (according to the International Classification of Disability and Health and Neuro-Functional Assessment, or NFA ICF-CY) were administered to VLBW infants at 24 months of corrected age. The primary outcome measure was severe functional disability, defined as cerebral palsy, bilateral blindness, deafness, an NFA ICF-CY of >2, a BSDI III cognitive composite score of <2 SD, or a GMDS-R global quotient score of <2 SD. Perinatal risk factors for severe functional disability were assessed through multivariate logistic regression analysis. Results: Among 502 VLBW survivors who completed the 24-month follow-up, 48 (9.6%) presented severe functional disability, of whom 27 had cerebral palsy (5.4%). Rates of severe functional disability and cerebral palsy were higher in neonates with a lower gestational age (p < 0.001). Overall, 147 infants (29.3%) were referred to neuromotor intervention. In the multivariate regression model, gestational age at birth OR 0.79; 95% CI 0.67-0.90; p = 0.001) and periventricular-intraventricular hemorrhage (OR 2.51; 95% CI 1.19-5.26; p = 0.015) were significantly associated with severe functional disability. Conclusion: Neuroprem 2 provides updated information on the neurodevelopmental outcomes of VLBW infants in a large Italian cohort. The overall rate of neurodevelopmental disabilities was quite lower than reported in the previous literature. These data indicate the need for structured follow-up programs from a national neonatal network perspective.

Assessment of child development in premature babies based on the ICF biopsychosocial model

BACKGROUND

The International Classification of Functionality (ICF) has been recommended to enable a broader and more holistic view of an individual's health condition. In addition, it works as an important reference for multiprofessional teams. In low-income countries, like Brazil, the attempts to systematize and incorporate the ICF model in health services has been a challenge.

AIM

The aim was to analyze the development of premature babies considering the biopsychosocial model of the ICF.

DESIGN

A longitudinal study.

SETTING

Maternity in the northeast Brazil.

POPULATION

Thirty-five premature babies were evaluated in the first stage and 20 in the second.

METHODS

Pre, perinatal, socioeconomic data and environmental factors were collected, and general movements assessed during the 38^th (±1.79) week of corrected gestational age. The Age and Stages Questionnaire (ASQ-3) was used to assess child development, in the 13^th (±1.50) month of life. The instruments were chosen with the objective of evaluating information necessary for the follow-up of premature infants and to represent the five domains of the ICF.

RESULTS

Of the 35 newborns initially evaluated, 20 were reassessed at 1 year of age and 70% were boys. In the function and structure domain, 55% exhibited altered general movements and 35% grade 1 intraventricular hemorrhage; in activity and participation, 15% displayed delayed communication, 20% delayed ample motor coordination, 40% fine motor coordination and problem resolution and 35% personal/social delay in the ASQ-3. Only one item of the personal factors (male sex) and function and structure domain (intraventricular hemorrhage) exhibited an association with atypical child development.

CONCLUSIONS

Given the susceptibility of premature newborn neurodevelopment and the magnitude of the biopsychosocial model of the ICF, even at this early stage of life, it was possible to observe the influence of personal factors, body function and structure domains on atypical child development.

CLINICAL REHABILITATION IMPACT

The care for the premature newborn with global look of the classification of functioning, disability and health.

Neuroprem: the Neuro-developmental outcome of very low birth weight infants in an Italian region

INTRODUCTION

The survival of preterm babies has increased worldwide, but the risk of neuro-developmental disabilities remains high, which is of concern to both the public and professionals. The early identification of children at risk of neuro-developmental disabilities may increase access to intervention, potentially influencing the outcome.

AIMS

Neuroprem is an area-based prospective cohort study on the neuro-developmental outcome of very low birth weight (VLBW) infants that aims to define severe functional disability at 2 years of age.

METHODS

Surviving VLBW infants from an Italian network of 7 neonatal intensive care units (NICUs) were assessed for 24 months through the Griffiths Mental Developmental Scales (GMDS-R) or the Bayley Scales of Infant and Toddler Development (BSDI III) and neuro-functional evaluation according to the International Classification of Disability and Health (ICF-CY). The primary outcome measure was severe functional disability at 2 years of age, defined as cerebral palsy, a BSDI III cognitive composite score < 2 standard deviation (SD) or a GMDS-R global quotients score < 2 SD, bilateral blindness or deafness.

RESULTS

Among 211 surviving VLBW infants, 153 completed follow-up at 24 months (72.5%). Thirteen patients (8.5%) developed a severe functional disability, of whom 7 presented with cerebral palsy (overall rate of 4.5%). Patients with cerebral palsy were all classified with ICF-CY scores of 3 or 4. BSDI III composite scores and GMDS-R subscales were significantly correlated with ICF-CY scores (p < 0.01).

CONCLUSION

Neuroprem represents an Italian network of NICUs aiming to work together to ensure preterm neuro-developmental assessment. This study updates information on VLBW outcomes in an Italian region, showing a rate of cerebral palsy and major developmental disabilities in line with or even lower than those of similar international studies. Therefore, Neuroprem provides encouraging data on VLBW neurological outcomes and supports the implementation of a preterm follow-up programme from a national network perspective.

Persistence of Effects of VLBW/PT Birth Status and Maternal Emotional Availability (EA) on Child EA Trajectories

Few studies have examined the longitudinal impact of birth status on the infant-mother relationship and on children's socio-emotional development. In the present study we investigated developmental patterns of such relationships [using the Emotional Availability (EA) Scales] in fullterm and VLBW/PT infants from infancy to emerging school age. Our objectives were to: (a) model the developmental trajectories of EA dimensions (maternal sensitivity, structuring, non-hostility; child responsiveness, involvement) in a VLBW/PT and fullterm sample, (b) identify potential effects of VLBW/PT status on these trajectories, and (c) determine whether the effects of VLBW/PT status on children's socio-emotional development (child EA) remained after accounting for the effect of maternal EA. Child-mother dyads (n = 109) were observed in home-based interactions (face-to-face and free play) when children were 6, 12, 18, and 57-months-old in fullterm (37-41 weeks, >2500 g; n = 48) and healthy VLBW/PT (26-32 weeks gestation, birth weight 800-1500 g, corrected for gestational age; n = 61) children. Developmental trajectories of maternal and child EA were assessed using multilevel growth modeling in Mplus. Results indicated that, even after controlling for maternal EA, there was a persistent negative effect of VLBW/PT birth status on child EA trajectories. Both initially and over time, VLBW/PT infants lagged behind their fullterm counterparts on levels of responsiveness and involvement with mothers. There was also a persistent positive effect of maternal EA (sensitivity and structuring) on child EA trajectories. Higher average levels of maternal sensitivity and structuring across time were also associated with higher and persistent levels of child responsiveness and involvement of their mothers. Importantly, results held after modeling both effects together, and after controlling for maternal education and child gender. Our results have implications for VLBW/PT children's development, the parent-child relationship, and integrating family level factors and relationship dimensions in early prevention and intervention programs.

A longitudinal ICF-CY-based evaluation of functioning and disability of children born with very low birth weight

This paper aims to describe the longitudinal changes in disability, defined by the International Classification of Functioning, Disability, and Health - Children and Youth version (ICF-CY) biopsychosocial model, and developmental outcomes in a cohort of 56 very low birth weight children over 14-20 months. We used a neurofunctional assessment, the Griffiths Mental Development Scales-Revised: 2-8 years (Griffiths 2-8) to evaluate psychomotor development and the ICF-CY questionnaire for ages 0-3 and 3-6 to address children's disability. Extension indexes on the basis of ICF-CY categories were computed, and longitudinal change was tested. Complete follow-up was available for 55 children (mean age 36.7 months, SD 6.7). Considering the sample as a whole, neurofunctional assessment, Griffiths score and disability were basically stable. When the subsample of children with the higher baseline functioning was taken into account, some degree of worsening, in terms of an increase in the number of impairments and limitations, was found. Our results show that disability profiles, neurofunctional assessment and global development were basically stable, except for the subgroup of children who were in the intermediate/high-functioning cluster at baseline. The increased disability among these children might be because of the possibility to observe a wider set of age-specific problems, such as emotional, regulation and social abilities that are not detectable at an early stage of development and that might lead to reduced participation in social activities.

Neurofunctional assessment at term equivalent age can predict 3-year neurodevelopmental outcomes in very low birth weight infants

AIM

Preterm infants are at high risk of developing motor delay, learning difficulties and behavioural problems and the availability of valid neurodevelopmental assessments is a major clinical issue. This study evaluated the relationship between preterm infants' neurofunctional assessment at term equivalent age and neurodevelopment outcome at three years of chronological age.

METHODS

Neurofunctional assessment was performed in 70 very low birth weight infants at term equivalent age and neurodevelopmental outcome was assessed at three years of chronological age with the Griffiths Mental Development Scale - Extended Revised.

RESULTS

At term equivalent age, 81% of the children had normal neurofunctional scores and 82.5% of those showed normal neurodevelopmental outcome at three years. Of the 19% who had impaired development at term equivalent age, 38.5% had neurodevelopmental delay at three years. Impaired neurofunctional status was associated with an increased risk of developmental delay in the global quotient (odds ratio 12.1) and locomotor sub-quotient (odds ratio 18.35) compared with normal neurofunctional status. Infants with sepsis or necrotising enterocolitis also faced a higher risk of neurodevelopmental delay.

CONCLUSION

Neurofunctional assessment performed at term equivalent age appeared to provide early identification of preterm infants at risk of neurodevelopmental delay at three years of chronological age.

Psychiatric diagnoses, emotional-behavioral symptoms and functional outcomes in adolescents born preterm with very low birth weights

Children born preterm with very low birth weight (VLBW; birth weight ≤1,500 g) run risks of neurodevelopmental disorders. Studies of adolescent outcome are relatively few. In this follow-up survey, we examined the emotional-behavioral symptoms, psychiatric diagnoses and functional status in a geographically-based birth cohort of VLBW adolescents (average 13.4 years) as registered in a level III center of a recently developed Asian country. Psychiatric interviews were conducted. Parents were asked to fill out the Child Behavioral Checklist and the Current Status Survey. Results revealed that neonatal survival rate was 75.7% (112/148). In the follow-up, 26.2% of the adolescents required individualized educational plan; 52.5% were with at least one neuropsychiatric diagnosis (e.g. cerebral palsy 24.6%, intellectual disabilities 21.3%, attention deficit/hyperactivity disorder 19.7%), and 32.8% of the participants were disabled. Logistic regression found that neonatal sepsis and grade III/IV intraventricular hemorrhage were most predictive of a disabled status in adolescence.
