El desarrollo de las habilidades narrativas en niños: una revisión sistemática de la literatura

Este artículo pretende identificar los modelos teóricos que describen el desarrollo de la narrativa oral en niños y establecer cuáles componentes del lenguaje influyen en dicho proceso. Con este propósito, llevamos a cabo una revisión sistemática de las investigaciones más recientes sobre este tema (2000-2019). Analizamos 10 estudios longitudinales que reportan resultados de medidas del lenguaje y la narrativa oral tomados durante el seguimiento de una población de niños y niñas por un periodo de al menos 12 meses. Estas medidas son la conciencia metalingüística, el lenguaje estructural y el discurso narrativo, entre otras. Nuestros resultados indican que la habilidad de contar un relato es uno de los mejores predictores del desarrollo del lenguaje en la etapa preescolar y del aprendizaje de la lectoescritura en la edad escolar. También encontramos que los modelos para explicar este proceso son escasos y que ignoran con frecuencia el componente pragmáticoThis paper aims to identify the theoretical models that describe the oral narrative development in children and establishing which language components influence this process. To that end, we conducted a systematic review of the most recent research output on this topic (2000-2019). We analyzed 10 longitudinal studies reporting results of language and oral narrative measures during a span of at least 12 months. Those measures are metalinguistic awareness, structural language, and narrative discourse, among others. Our results indicate that the ability to tell a story is one of the best predictors of language development at early childhood education age, as well as literacy achievement at school age. We also found that previous models aiming to explain this process are scarce, often ignoring the pragmatic component of languag

Animal models for COVID-19

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the aetiological agent of coronavirus disease 2019 (COVID-19), an emerging respiratory infection caused by the introduction of a novel coronavirus into humans late in 2019 (frst detected in Hubei province, China). As of 18 September 2020, SARS-CoV-2 has spread to 215 countries, has infected more than 30 million people and has caused more than 950,000 deaths. As humans do not have pre-existing immunity to SARS-CoV-2, there is an urgent need to develop therapeutic agents and vaccines to mitigate the current pandemic and to prevent the re-emergence of COVID-19. In February 2020, the World Health Organization (WHO) assembled an international panel to develop animal models for COVID-19 to accelerate the testing of vaccines and therapeutic agents. Here we summarize the fndings to date and provides relevant information for preclinical testing of vaccine candidates and therapeutic agents for COVID-19.info:eu-repo/semantics/acceptedVersio

Data Descriptor: An open resource for transdiagnostic research in pediatric mental health and learning disorders

Technological and methodological innovations are equipping researchers with unprecedented capabilities for detecting and characterizing pathologic processes in the developing human brain. As a result, ambitions to achieve clinically useful tools to assist in the diagnosis and management of mental health and learning disorders are gaining momentum. To this end, it is critical to accrue large-scale multimodal datasets that capture a broad range of commonly encountered clinical psychopathology. The Child Mind Institute has launched the Healthy Brain Network (HBN), an ongoing initiative focused on creating and sharing a biobank of data from 10,000 New York area participants (ages 5–21). The HBN Biobank houses data about psychiatric, behavioral, cognitive, and lifestyle phenotypes, as well as multimodal brain imaging (resting and naturalistic viewing fMRI, diffusion MRI, morphometric MRI), electroencephalography, eyetracking, voice and video recordings, genetics and actigraphy. Here, we present the rationale, design and implementation of HBN protocols. We describe the first data release (n =664) and the potential of the biobank to advance related areas (e.g., biophysical modeling, voice analysis

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Consecuencias de las acciones del Plan Colombia en una zona generadora de agua. Caso de la comunidad indígena Yanacona en el corregimiento de Valencia (Cauca) - macizo colombiano

El Pueblo Yanacona habita en el Macizo Colombiano, al suroccidente del país, región que por sus características físicas y ambientales -clima, hidrografía, orografía, entre otros-, es de suma importancia para el equilibrio ambiental del país, así como para el desarrollo y permanencia en el tiempo del pueblo indígena Yanacona. Dicho pueblo basa su cultura en la estrecha relación que ha construido entre el hombre y la naturaleza, de tal forma que el quehacer diario se lleva a cabo por la importancia del bosque, del páramo, y particularmente, por la presencia del agua

Ambiguity potentiates effects of loneliness on feelings of rejection

For social species, having strong and high-quality social relationships is an important safety cue. Loneliness occurs when an individual perceives they have insufficient relationships resulting in feelings of lack of safety. States of perceived unsafety are linked to an increased tendency to construe ambiguous information—information lacking a unique clear interpretation--as threatening. Here, we explore whether the ambiguity of social cues of interpersonal rejection moderates effects of loneliness on feelings of rejection while undergoing social exclusion. Data were collected in 2021; 144 adults completed a progressive social exclusion paradigm where they were randomly assigned to be equally included, excluded, or over-included. Social exclusion/inclusion cues became more pronounced over the course of multiple rounds of a ball-tossing game (Cyberball) resulting in a scenario where ambiguity was highest in earlier rounds and decreased over time. Participants reported feelings of loneliness prior to the task and feelings of rejection throughout the task. Results demonstrated that higher loneliness predicted increased feelings of rejection regardless of exclusion condition. Notably, this positive relationship was strongest during earlier rounds when social cues were most ambiguous. These findings contribute to our understanding of how loneliness modulates social perception to enable organisms to adequately adapt to changing circumstances
