Profiling the Longitudinal Development of Babbling in Infants with Cerebral Palsy: Validation of the Infant Monitor of Vocal Production (IMP) Using the Stark Assessment of Early Vocal Development-Revised (SAEVD-R).

AIM: We compared early vocal development in children "at risk" for cerebral palsy (CP) with typically developing (TD) infants aged 6 to 15 months using the SAEVD-R, investigating potential pre-linguistic markers of communication impairment. Additionally, we sought to examine the agreement between the SAEVD-R and IMP, which uses parent report, in identifying departure from typical vocal development in at-risk infants. METHOD: Utilising a longitudinal cohort study, >10,000 vocalisations of 33 infants (15 at risk for CP and 18 TD) were assessed at 6, 9, 12, and 15 months using the SAEVD-R. Generalised linear mixed models (GLMMs) compared groups, and Spearman correlations explored IMP ceiling scores and SAEVD-R measures. RESULTS: At 6 months, both TD and CP groups reached SAEVD-R vocalisation level 3 (expansion). By 9 months, 51% of TD infants progressed to advanced babbling (levels 4 and 5), while 80% of at-risk infants remained at level 3. At 12 and 15 months, over 90% of TD children advanced, compared to 67% at 12 months and 53% at 15 months for at-risk infants, who stayed at the pre-canonical stage. Strong correlations were found between IMP scores and vocalisation levels at 9 and 12 months. Remaining at the pre-canonical stage at 12 months correlated with delayed vocal development as per IMP scores. INTERPRETATION: TD infants achieved higher SAEVD-R levels than at-risk infants. At 12 months, IMP scores effectively identified infants with speech-like vocalisation difficulties, demonstrating its clinical utility in identifying atypical vocal development in infants at risk for CP.

ARCHS: adult recipients of cochlear implants: health and social long-term outcomes-a state-specific and national population-based retrospective cohort study protocol.

INTRODUCTION: While the majority of adults with severe-to-profound hearing loss and poor speech perception outcomes with hearing aids benefit from receiving a cochlear implant, the long-term health and social benefits for implant recipients are yet to be explored. The objective of the ARCHS research is to provide a better understanding of the health and social factors that play a role in the lives of adults with a cochlear implant up to 10 years after the procedure. METHOD AND ANALYSIS: This research will involve conducting two retrospective cohort studies of adults aged ≥18 years who received a cochlear implant during 2011-2021 using linked administrative data first within New South Wales (NSW) and second Australia-wide. It will examine health service use and compare health and social outcomes for younger (18-64 years) and older (≥65 years) cochlear implant recipients. ETHICS AND DISSEMINATION: Ethical approval was received from the NSW Population Health Services Research Ethics Committee for the NSW cohort study (Reference: 2022/ETH00382/2022.07) and from the Macquarie University ethics committee for the national cohort study (Reference: 520221151437084). Research findings will be published in peer-reviewed journals and presented at scientific conferences.

Exploring the Functional Impact of Childhood Vision Impairment: An e-Delphi Study.

The principles of the World Health Organization's International Classification of Function, Disability and Health have been embraced globally as a framework to support people with disability. This framework recognizes the functional needs of a person, as well as their medical diagnosis. However, the challenge of assessing the functional impact of disability to determine a person's needs and eligibility for support remains an issue. One example is that of childhood vision impairment, where a child's eligibility is often gauged from their visual performance in a clinical environment, a setting that is far removed from the child's real-world environment. Such clinical environments fail to reveal those factors that have a functional impact and affect the child's continuous visual function in their everyday situation. To examine this issue a three round modified e-Delphi technique was applied to explore the functional impact of childhood vision impairment. A panel of experienced Australian orthoptists and specialist teachers in vision impairment was convened, and the recently revised vision classifications in the World Health Organization International Statistical Classification of Diseases and Health Related Problems Version 11 were reviewed and modified for their application to children. This paper describes the e-Delphi technique and the major study outcomes including the modifications proposed by the study's participants, and the emerging paradigm that progresses an understanding of the functional impact of childhood vision impairment.
