RESUMO
BACKGROUND: Infant crying is the first attempt babies use to communicate during their initial months of life. A misunderstanding of the cry message can compromise infant care and future neurodevelopmental process. METHODS: An exploratory study collecting multimodal data (i.e., crying, electroencephalography (EEG), near-infrared spectroscopy (NIRS), facial expressions, and body movements) from 38 healthy full-term newborns was conducted. Cry types were defined based on different conditions (i.e., hunger, sleepiness, fussiness, need to burp, and distress). Statistical analysis, Machine Learning (ML), and Deep Learning (DL) techniques were used to identify relevant features for cry type classification and to evaluate a robust DL algorithm named Acoustic MultiStage Interpreter (AMSI). RESULTS: Significant differences were found across cry types based on acoustics, EEG, NIRS, facial expressions, and body movements. Acoustics and body language were identified as the most relevant ML features to support the cause of crying. The DL AMSI algorithm achieved an accuracy rate of 92%. CONCLUSIONS: This study set a precedent for cry analysis research by highlighting the complexity of newborn cry expression and strengthening the potential use of infant cry analysis as an objective, reliable, accessible, and non-invasive tool for cry interpretation, improving the infant-parent relationship and ensuring family well-being.

OBJECTIVE: We have analyzed social and leadership abilities in children with ADHD and their relationship with execution of tasks involving sustained attention and inhibitory control. PATIENTS AND METHODS: A retrospective analysis of 170 patients with ADHD was performed. We evaluated leadership and social abilities, measured through the Behavior Assessment System for Children (BASC) and their relations with the results of different neuropsychological tests, including Wechsler scale for children (WISC-IV) and Conners' continuous performance (CPT II). RESULTS: In the differential analysis between the IQ, results of the tests and their relation to BASC scores, a statistically significant relation was observed between attentional capacity expected according to the patient's intelligence and social skills scores (according to BASC filled out by mothers and teachers) and leadership (according to all informants) sections. CONCLUSIONS: Attentional difficulties are closely related to social competence in patients with ADHD, either by a direct cause-effect relationship or a shared dysexecutive substrate of this disorder.

INTRODUCTION: Numerous studies have documented that children with attention deficit hyperactivity disorder (ADHD) show a low social competence. OBJECTIVE: To compare the symptomatic severity of ADHD, as well as associations to different subtypes, sex and comorbidities, with social functioning ("ability" and "leadership") estimated through a Behavior Assessment System for Children (BASC) for parents and teachers. PATIENTS AND METHODS: We have retrospectively analyzed 170 patients with ADHD, diagnosed between 2007 and 2010. Social "ability," "leadership," "hyperactivity" and "attention deficit" sections of BASC and cardinal symptoms of ADHD measured through a Spanish scale for de evaluation of DHD (E-DHD) were registered. Results of these variables are analyzed according to the normative data by age and sex, and processed in Z values. RESULTS: The ratings for social skills were significantly lower in patients with conduct disorder or oppositional defiant disorder as informed by parents (p<0.05). Symptomatic intensity of ADHD showed significant (p<0,001) and inverse relation with social "ability" as parents. "Attention-deficit" scores were related with social "ability" and "leadership" as parents and teachers. CONCLUSIONS: Intensity of attention deficit was the only variable that showed a significant relation with the social skills and leadership according to the BASC scores, independently of the informer.
