Language Development Survey Provides a Useful Screening Tool for Language Delay in Preterm Infants
ABSTRACT Developmental language disorder has been reported in 3% to 10% of term infants and 30% of preterm infants (<34 weeks gestation). Screening for language delay in preterm infants can be costly and time-consuming. The objective of this study was to assess the expressive language development of preterm infants using the Language Development Survey (LDS). A total of 178 preterm infants born at 23 to 34 weeks between 2006 and 2008 were enrolled. The LDS was completed by parents between 22 and 26 months at or shortly before 2-year neurodevelopmental assessment using the Bayley III Scale. A total of 26% of former preterm patients had language delay, using LDS. Significant correlations were observed between LDS results and Bayley III scores. Male gender and public health insurance were the most important risk factors for language delay in this cohort. Expressive language delay was present in 26% of preterm infants. LDS is a suitable and inexpensive screening tool for assessing language delay in preterm infants.

ABSTRACT: The Bayley Scales of Infant and Toddler Development - 3rd Edition (Bayley-III) was updated to enhance its usefulness for contemporary child developmental assessment. However, recent data in Western countries have implicated the overestimation of child development by the new instrument. This study aimed to investigate the psychometric features of the Bayley-III for term and preterm infants in Taiwan. Forty-seven term infants and 167 preterm infants were prospectively examined with the Bayley Scales of Infant Development - 2nd Edition (BSID-II) and the Bayley-III at 6, 12, 18, and 24 months of age (corrected for prematurity). The psychometric properties examined included reliability, construct validity, and known-group validity. The intra- and inter-rater reliabilities of the Bayley-III were good to excellent. The correlations between the BSID-II and Bayley-III raw scores were good to excellent for the cognitive and motor items and low to excellent for the language items. Term infants achieved higher composite scores than preterm infants on all of the Bayley-III scales (p<0.05). However, their rates of developmental delay were lower than the previously established prevalence estimates. The Bayley-III cut-off composite score was adjusted 10-20, 1-13, and 12-24 points higher than 70 for optimal prediction of cognitive, language, and motor delay, respectively, as defined by the BSID-II index score<70. The Bayley-III is a reliable instrument that extends its previous edition, especially in early language assessment. However, the upward adjustment of its cut-off score is recommended for the accurate identification of developmental delay in term and preterm Taiwanese infants.Research in developmental disabilities 09/2013; 34(11):3875-3883.

ABSTRACT: Neuro-evolutive development from birth until the age of six years is a decisive factor in a child's quality of life. Early detection of development disorders in early childhood can facilitate necessary diagnosis and/or treatment. Primary-care pediatricians play a key role in its detection as they can undertake the preventive and therapeutic actions requested to promote a child's optimal development. However, the lack of time and little specific knowledge at primary-care avoid to applying continuous early-detection anomalies procedures. This research paper focuses on the deployment and evaluation of a smart system that enhances the screening of language disorders in primary care. Pediatricians get support to proceed with early referral of language disorders. The proposed model provides them with a decision-support tool for referral actions to trigger essential diagnostic and/or therapeutic actions for a comprehensive individual development. The research was conducted by starting from a sample of 60 cases of children with language disorders. Validation was carried out through two complementary steps: first, by including a team of seven experts from the fields of neonatology, pediatrics, neurology and language therapy, and, second, through the evaluation of 21 more previously diagnosed cases. The results obtained show that therapist positively accepted the system proposal in 18 cases (86%) and suggested system redesign for single referral to a speech therapist in three remaining cases.Sensors 06/2013; 13(6):7522-45.

ABSTRACT: La investigación y desarrollo de sistemas telemáticos en e-salud se ha limitado típicamente al despliegue de soluciones centradas en el acceso a la historia clínica electrónica. El presente trabajo aborda la complejidad de diseñar un servicio telemático capaz de ayudar al pediatra de atención primaria en el proceso de decidir si derivar o no a atención especializada a un niño de hasta seis años con posibles trastornos del lenguaje. Con esta finalidad, se ha construido una ontología a partir del análisis sistemático de 21 casos de niños ya diagnosticados y se ha desarrollado una plataforma web que facilita al pediatra su labor de detección precoz. Asimismo, se ha implementado una plataforma web para el especialista que permite validar la efectividad del sistema construido. El proceso de evaluación se ha completado con 21 casos de niños, diferentes de los 21 originales y extendiéndose a 160 niños de una escuela infantil.XI Jornadas de Ingeniería Telemática, Granada (Spain); 10/2013
