standards and models proposed by several ministries of education were analyzed, among them Australia, Belgium, Canada, Chile, Spain, the United States, France, Norway and others, as well as organizations such as UNESCO or ISTE, and the researches of prestigious universities (Pozos Pérez, 2009; Carrera y Coiduras, 2012; Prendes y Gutiérrez, 2013). This study determines a preliminary profile of teachers in the area of mathematics, which describes the dimensions, competencies and indicators developed by teachers of a university in Ecuador and validated by a group of international experts in digitals competence teacher. The results show that the profile is composed by 44 indicators corresponding to 21 digital competences that respond to the basic, intermediate and advanced levels of domain, use and innovation in five areas: information and information literacy, communication and collaboration, creation of digital content, security and problem solving

Introduction: Critically ill children in the pediatric intensive care unit (PICU) are at high risk for developing nutritional deficiencies and undernutrition is known to be a risk factor for morbidity and mortality. Malnutrition represents a continuous spectrum ranging from marginal nutrient status to severe metabolic and functional alterations and this in turn, affects clinical outcome. Objectives: The aim of the study was to assess nutritional status of critically ill children admitted to the PICU and its association to clinical outcomes. Methods: Critically ill children age 6 months to 18 years were prospectively enrolled on PICU admission. Nutritional status was assessed by weight for age (WFA: underweight), weight for height (WFH: wasting), height for age (HFA: stunting) z-scores and mid upper arm circumference (MUAC: wasting) according to the WHO. (1,2) Malnutrition was defined as mild, moderate, and severe if z-scores were > −1, > − 2, and > −3, respectively. Hospital and PICU length of stay (LOS), duration of mechanical ventilation (MV), and risk of mortality (ROM) by the Pediatric Index of Mortality 2 (PIM2) were obtained. Sensitivity and specificity of the MUAC to identify children with wasting (WFH) were calculated. Results: Two hundred and fifty children (136 males), aged 81 months (23-167; median (25-75 th IQR)), were prospectively included in the study. The hospital LOS was 8 (4-16) days; PICU LOS: 2 (1-4) days; duration of MV, 0 (0-1.5) days;
