ObjectivesTo report on knowledge translation strategies and outcomes from the implementation of the early detection guidelines for cerebral palsy (CP) in a state-wide tertiary early intervention (EI) service and investigate the impact of social determinants on clinical services.DesignRetrospective longitudinal cohort study.SettingThe Western Australia tertiary paediatric EI service.ParticipantsEI clinicians, consumers and children using the EI service.Outcome measuresKnowledge translation strategies including consumer perspectives, clinician training and Communities of Practice (CoP) guided implementation. We measured changes in referral number and age, delivery of early detection and intervention following the implementation of the guidelines. Exposure to adverse childhood experiences (ACEs), appointment non-attendance (DNA) rates, remoteness and socioeconomic quintiles were used to measure social determinants of health using negative binomial (Incidence Rate Ratios, IRR) and logistic regression (Odds Ratios, ORs).ResultsTen consumers participated in Focus Groups, 100 clinicians were trained and 22 clinicians established a monthly CoP. Referrals increased fourfold to 511 children. Corrected gestational age at referral decreased from a median of 16.1 to 5.1 months (pConclusionsImplementation strategies reduced referral age and improved the delivery of early detection assessments. Further investigation of the association between social disadvantage, DNA risk and ACE score is required in the development of a state-wide early detection network.

BACKGROUND This study investigated mother-infant interactions, including maternal maintaining of infant attentional focus and sensitivity, with infants with congenital severe and profound visual impairment (VI) and the association with developmental trajectories from one to three years. METHOD Fifty-five infants and mothers were video-recorded playing together with a standard set of toys at Time 1 (T1) mean age 12.95 months (8.13-17.05 months). Maintain was categorized as the mother following and maintaining the child's focus, and Sensitivity, the mother's responsiveness and contingency to infant behaviour. Vision level was measured using the Near Detection Scale. Cognition and language were measured at T1, 12 months later (T2) and 24 months later (T3) using the Reynell-Zinkin Scales. RESULTS Cross-sectional analyses showed that mothers of infants with severe VI (basic form vision) produced higher rates of Maintain compared to those with children with profound VI (light perception at best). Linear mixed-effects models examining developmental progression from T1 to T3 (controlling for vision level) showed an average increase of 5 DQ points (CI 95%: 1.03-9.08) in verbal comprehension for higher Sensitivity. No significant findings were found for Maintain. CONCLUSIONS The findings suggest that mother-infant interactions (maternal Maintain) are associated with level of vision at infancy, but only maternal Sensitivity has a long-term positive association with advances in verbal comprehension from infancy to about three years. They highlight the need for incorporating strategies related to parent-infant interactions, including increased sensitivity, into early intervention for children with visual impairment.

To investigate detection vision development in infants and toddlers with congenital disorders of the peripheral visual system (CDPVS) and severe to profound visual impairment (SVI/PVI).This was a longitudinal observational investigation of a cohort of infants with CDPVS (entry age 8-16mo) followed up 12 months later. Detection vision (Near Detection Scale [NDS]) and resolution acuity (Keeler Acuity Cards [KAC]) were assessed at each time point. Relationships between detection vision, resolution acuity, and age were investigated.The study cohort comprised 80 children (39 females, 41 males), mean age 13 months (Time 1) and 26 months (Time 2); 22 (27.5%) with PVI (light perception at best) and 58 (72.5%) with SVI (basic 'form' vision) at Time 1. All children achieved a measure with the NDS, however only 35 per cent and 56 per cent at Time 1 and Time 2 respectively did so on KAC. Those with PVI at Time 1 showed no further improvement at Time 2, but 87 per cent of children with SVI showed improvement in vision. The median change in NDS score was 1.0 (range 1-7, SD 1.68).Vision development continues after 12 months of age in many toddlers if they have basic 'form' vision. A measure of detection vision is feasible in very young children when resolution acuity measurement is not achievable.The Near Detection Scale (NDS) can measure low levels of vision when acuity is not otherwise measurable. Vision can improve in toddlers with severe visual impairment who have some 'form' vision. Infants with light perception at best by 12 months are unlikely to show improvement in vision. There is a moderate negative relationship between the NDS and resolution acuity results.

AIM This study examined cross-sectional and longitudinal patterns of parenting stress, adult anxiety, and depression in mothers of children with profound or severe visual impairment (PVI or SVI) at 1 year and 2 years of age. METHOD Mothers of a national longitudinal cohort (OPTIMUM Project) of infants with congenital disorders of the peripheral visual system and PVI (light perception at best) or SVI (basic 'form' vision of non-light reflecting objects) participated. Infant age at baseline (T1 ) was 8 to 16 months. Mothers completed the Parenting Stress Index - Short Form and the Hospital Anxiety and Depression Scale at T1 (n=79) and at follow-up 12 months later (T2 ) (n=73). RESULTS Mothers of the total group had higher parenting stress levels (34.6% in clinical range) than community normative data at T1 (p=0.017). Mothers of infants in the PVI subgroup had elevated stress at T1 (p=0.014) and T2 (p=0.009). The PVI subgroup was also elevated in the Difficult Child subscale at T2 (p=0.001). Within-sample differences in parenting stress between the visual impairment subgroups were found at T2 only: the PVI subgroup scored higher than the SVI subgroup (p=0.029). Adult anxiety and depression in the total group were not elevated compared with community normative data at T1 and T2 ; however, higher parenting stress was related to raised adult anxiety and depression levels at T1 and T2 (p=0.001). Regression analysis found parenting stress and lower child vision level (T1 ) predicted parenting stress (T2 ) (p=0.001; 42% variance). INTERPRETATION Mothers of 1-year-old infants with visual impairment showed raised risk for parenting stress, which continued to be elevated for children with PVI and those perceived as 'difficult' at 2 years. This was also a psychological risk, with greater adult anxiety and depression in those mothers with raised parenting stress. The clinical significance is that identification of parenting stress and targeted parenting, and behavioural support of the child in the first years of life is highly indicated. WHAT THIS PAPER ADDS Mothers of infants with visual impairment are at increased risk of parenting stress. Parenting stress was higher in mothers of children with profound visual impairment than those with severe visual impairment. High levels of parenting stress and lower infant vision at 1 year of age predicted higher parenting stress at 2 years of age.

Objective Young children with congenital visual impairment (VI) are at increased risk of behavioral vulnerabilities. Studies on ‘at risk’ populations suggest that frontal EEG asymmetry may be associated with behavioral risk. We investigated frontal asymmetry at 1 year (Time 1), behavior at 2 years (Time 2) and their longitudinal associations within a sample of infants with VI. Frontal asymmetry in the VI sample at 1 year was also compared cross-sectionally to an age-matched typically sighted (TS) group. Methods At Time 1, 22 infants with VI and 10 TS infants underwent 128-channel EEG recording. Frontal asymmetry ratios were calculated from power spectral density values in the alpha frequency band. At Time 2, Achenbach Child Behavior Checklist data was obtained for the VI sample. Results 63.6% of the VI sample and 50% of the TS sample showed left frontal asymmetry; no significant difference in frontal asymmetry was found between the two groups. 22.7% of the VI sample had subclinical to clinical range ‘internalizing’ behavior difficulties. Greater left frontal asymmetry at one year was significantly associated with greater emotionally reactive scores at two years within the VI sample ( r = 0.50, p = 0.02). Conclusions Left frontal asymmetry correlates with later behavior risk within this vulnerable population. Significance These findings make an important first contribution regarding the utility of frontal EEG asymmetry as a method to investigate risk in infants with VI.

To investigate the effects of home-based early intervention in children with severe visual impairment (SVI) using the Developmental Journal for babies and young children with visual impairment (DJVI).A longitudinal observational study was undertaken with a national cohort (OPTIMUM) of infants with congenital disorders of the peripheral visual system (CDPVS) and profound-SVI; and followed up after 12 months and 24 months. Intervention was categorized according to the practitioner diary records of their usual practice over 12 months from baseline comparing those receiving the DJVI and those receiving 'Other Support'. Outcome measures of cognition and language, behaviour difficulties, parenting stress, and satisfaction with parent-practitioner partnership were collected.In the 54 children (26 males, 28 females, baseline mean age 13.5mo, SD 2.3mo, range 8-17mo) with 'total' CDPVS (including 16 'complex' and 38 'simple' with or without known brain disorder respectively), linear mixed effects pointed towards acceleration in sensorimotor understanding and expressive language especially in the 'simple' subsample (11.72 developmental quotient, 95% confidence interval -1.17 to 24.61, p0.05) in those receiving the DJVI. Vision level also predicted outcomes (p0.05). The DJVI group showed improvements in behavioural withdrawal (ηInfants and young children with visual impairment receiving home-based early intervention using the DJVI with a structured developmental approach had better outcomes than those receiving 'other' home-based early interventions. Moderate to large effect improvements were found in child cognition and language, behaviour and parenting stress and the perceived practitioner-parent relationship, although cognition did not reach 5% significance level.Early intervention using the Developmental Journal for babies and young children with visual impairment was associated with enhanced developmental outcomes compared to other approaches. Improvements were also found in child behaviour, parenting stress, and perceived parent practitioner outcomes. Type and complexity of visual impairment also influenced outcomes.INTERVENCIÓN TEMPRANA DOMICILIARIA EN LACTANTES Y NIÑOS PEQUEÑOS CON DISCAPACIDAD VISUAL USANDO EL DIARIO DE DESARROLLO: ESTUDIO LONGITUDINAL DE COHORTE: OBJETIVO: Investigar los efectos de la intervención temprana en el hogar en niños con discapacidad visual grave utilizando el Diario de Desarrollo para bebés y niños pequeños con discapacidad visual (DJVI).

Introduction Cerebral palsy (CP) is the most common childhood physical disability, with 80% estimated to be in low-middle-income countries. This study aims to (1) determine the accuracy of General Movements (GMs)/Hammersmith Infant Neurological Examination (HINE) for detecting CP at 18 months corrected age (CA); (2) determine the effectiveness of a community-based parent-delivered early intervention for infants at high risk of CP in West Bengal, India (Learning through Everyday Activities with Parents for infants with CP; LEAP-CP). Methods This study comprises two substudies: (1) a study of the predictive validity of the GMs and HINE for detecting CP; (2) randomised, double-blinded controlled trial of a novel intervention delivered through peer trainers (Community Disability Workers, CDW) compared with health advice (15 fortnightly visits). 142 infants at high risk of CP (‘absent fidgety’ GMs; ‘high risk score’ on HINE) aged 12–40 weeks CA will be recruited to the intervention substudy, with infants randomised based on a computer-generated sequence. Researchers will be masked to group allocation, and caregivers and CDWs naive to intervention status. Visits will include therapeutic modules (goal-directed active motor/cognitive strategies and LEAP-CP games) and parent education. Health advice is based on the Integrated Management of Childhood Illness, WHO. Infants will be evaluated at baseline, post intervention and 18 months CA. The primary hypothesis is that infants receiving LEAP-CP will have greater scaled scores on the Pediatric Evaluation of Disability Inventory—Computer Adaptive Test (mobility domain) at 18 months compared with health advice. Secondary outcomes include infant functional motor, cognitive, visual and communication development; infant growth; maternal mental health. Ethics and dissemination This study is approved through appropriate Australian and Indian ethics committees (see in text) with families providing written informed consent. Findings from this trial will be disseminated through peer-reviewed journal publications and conference presentations. Trial registration number 12616000653460p; Pre-results.

Aim To investigate how vision relates to early development by studying vision and cognition in a national cohort of 1-year-old infants with congenital disorders of the peripheral visual system and visual impairment. Method This was a cross-sectional observational investigation of a nationally recruited cohort of infants with ‘simple’ and ‘complex’ congenital disorders of the peripheral visual system. Entry age was 8 to 16 months. Vision level (Near Detection Scale) and non-verbal cognition (sensorimotor understanding, Reynell Zinkin Scales) were assessed. Parents completed demographic questionnaires. Results Of 90 infants (49 males, 41 females; mean 13mo, standard deviation [SD] 2.5mo; range 7–17mo); 25 (28%) had profound visual impairment (light perception at best) and 65 (72%) had severe visual impairment (basic ‘form’ vision). The Near Detection Scale correlated significantly with sensorimotor understanding developmental quotients in the ‘total’, ‘simple’, and ‘complex’ groups (all p

The role of vision and vision deprivation in the development of executive function (EF) abilities in childhood is little understood; aspects of EF such as initiative, attention orienting, inhibition, planning and performance monitoring are often measured through visual tasks. Studying the development and integrity of EF abilities in children with congenital visual impairment (VI) may provide important insights into the development of EF and also its possible relationship with vision and non-visual senses. The current study investigates non-visual EF abilities in 18 school-age children of average verbal intelligence with VI of differing levels of severity arising from congenital disorders affecting the eye, retina, or anterior optic nerve. Standard auditory neuropsychological assessments of sustained and divided attention, phonemic, semantic and switching verbal fluency, verbal working memory, and ratings of everyday executive abilities by parents were undertaken. Executive skills were compared to age-matched typically-sighted (TS) typically-developing children and across levels of vision (mild to moderate VI [MVI] or severe to profound VI [SPVI]). The results do not indicate significant differences or deficits on direct assessments of verbal and auditory EF between the groups. However, parent ratings suggest difficulties with everyday executive abilities, with the greatest difficulties in those with SPVI. The findings are discussed as possibly reflecting increased demands of behavioral executive skills for children with VI in everyday situations despite auditory and verbal EF abilities in the typical range for their age. These findings have potential implications for clinical and educational practices.

ObjectiveTo present a structured approach for an outpatient consultation for a child with developmental disability who may have an ocular or visual disorder.MethodReview of relevant literature and description of the approach to ocular and visual assessment which could be used by any paediatrician.ConclusionA systematic approach to history, observation and examination of a child with a developmental disability will assist in identifying a possible visual problem. A structured referral letter will ensure that the child will receive the most appropriate assessment to clarify the problem and appropriate management in the eye clinic.

Background Antibiotics used for women in spontaneous preterm labour without overt infection, in contrast to those with preterm rupture of membranes, are associated with altered functional outcomes in their children. Methods From the National Pupil Database, we used Key Stage 2 scores, national test scores in school year 6 at 11 years of age, to explore the hypothesis that erythromycin and co-amoxiclav were associated with poorer educational outcomes within the ORACLE Children Study. Results Anonymised scores for 97% of surviving children born to mothers recruited to ORACLE and resident in England were analysed against treatment group adjusting for key available socio-demographic potential confounders. No association with crude or with adjusted scores for English, mathematics or science was observed by maternal antibiotic group in either women with preterm rupture of membranes or spontaneous preterm labour with intact membranes. While the proportion receiving special educational needs was similar in each group (range 31.6–34.4%), it was higher than the national rate of 19%. Conclusions Despite evidence that antibiotics are associated with increased functional impairment at 7 years, educational test scores and special needs at 11 years of age show no differences between trial groups.
