Chagas disease vectors can ingest several times their own volume in blood with each meal. This ad libitum feeding causes an intense process of diuresis, inducing the insect to eliminate a large quantity of urine and faeces. To ensure diuresis, the speed of circulation of the haemolymph is increased.

Yet, it remains unclear whether caregivers' history of language and reading difficulties is associated with caregiver self-efficacy.

Emerging research has provided valuable insights into the structural characteristics of the bilingual brain from studies of bilingual adults; however, there is a dearth of evidence examining brain structural alterations in childhood associated with the bilingual experience. This study examined the associations between bilingualism and white matter organization in bilingual children compared to monolingual peers leveraging the large-scale data from the Adolescent Brain Cognitive Development (ABCD) Study. Then, 446 bilingual children (ages 9-10) were identified from the participants in the ABCD data and rigorously matched to a group of 446 monolingual peers.

Article Synopsis
  • The study aimed to evaluate how effective two language measures—mean length of utterance in words (MLUw) and percentage of grammatical utterances (PGU)—are in diagnosing developmental language disorder (DLD) in Spanish-English bilingual children.
  • Researchers analyzed language samples from 74 bilingual children, half with DLD and half without, using storytelling tasks in both languages to collect data.
  • Results indicated that a model incorporating PGU, MLUw, and age provided the highest diagnostic accuracy, suggesting that these measures can effectively distinguish between bilingual children with and without DLD.

Purpose: The purpose of this study was to examine the growth of previously established clinical markers of developmental language disorder (DLD) in Spanish-speaking bilingual children with and without DLD.

Method: Forty-three bilingual children with DLD and 57 typically developing children were tested 3 times over a 2-year period. Their average age at Time 1 was 5;10 (years;months).
