ABSTRACT Introduction. The relevance of neurosciences research for promoting child development is recognized worldwide by policy makers, teachers and parents. However, it is essential that this highly specialized knowledge be interpreted and translated into concrete strategies and instruments to be applied at school, at home, and in specialized care settings for children with neurodevelopmental disorders (TND). Methods. A selection of the main results of neurodevelopment research is presented, published by the Cuban Neurosciences Center (CNEURO) in peer-reviewed journals. Results and Discussion. Behavioral and neuroimaging studies of the neurocognitive foundations of learning processes and academic achievement allowed for identifying risk indicators for TND and supporting the design of instruments for early detection, cognitive profiling and individualized attention of children. It is concluded that the results demonstrate the process of translation and application of scientific evidence into instruments and strategies for the protection of the nation's mental capital and its integration into national health and education programs dedicated to early child care and education.

RESUMEN Introducción. La relevancia de las evidencias provenientes de las neurociencias para potenciar el desarrollo infantil y el rendimiento académico ha sido reconocida por formuladores de políticas, maestros y padres de todo el mundo. Sin embargo, ha sido indispensable que este conocimiento altamente especializado sea interpretado y traducido en estrategias e instrumentos concretos a aplicar en la escuela, el hogar y los escenarios de atención especializada de los niños que presentan trastornos del neurodesarrollo (TND). Métodos. Se presenta una selección de los principales resultados de la línea de neurodesarrollo publicados por el Centro de Neurociencias de Cuba (CNEURO) en revistas arbitradas por pares. Resultados y Discusión. Los estudios conductuales y de neuroimágen de las bases neuro-cognitivas de los procesos de aprendizaje y el rendimiento académico permitieron identificar indicadores de riesgo de TND y fundamentar el diseño de instrumentos para la detección temprana, caracterización del perfil cognitivo y la atención individualizada de los niños. Se concluyó que los resultados demostraron el proceso de traducción y aplicación de las evidencias científicas en instrumentos y estrategias para la protección del capital mental de la nación y su integración a los programas nacionales de salud y educación, dedicados a la atención temprana del desarrollo infantil.

ABSTRACT Introduction: Confinement due to COVID-19 pandemic that children are exposed to favors child abuse. Objectives: To describe different ways of child abuse that can occur during confinement due to COVID-19. Methods: The research was carried out from March to June, 2020. As primary information sources were used: books, scientific journals and thesis; and as secondary sources: Scielo and Redalyc databases, and UNICEF and UNESCO documents. The terms and keywords used in the search were: family, child abuse, quarantine, COVID-19. Results: It was defined the concept of abuse and the risk factors involved. It was mentioned physical abuse, abandonment, sexual abuse, abuse of power, and psychological abuse. There were stated the psychological reactions that children might present due to the impact of confinement. It was also addressed the importance of detecting children abuse, and some directions in this regard were given to the parents. Final considerations: Alert state generated by COVID-19 has implanted new stressors which can trigger abuse situations in the children population like: violence while raising children as a way of physical abuse, abandonment practices although the family members are living together, children and adolescents´ sexual abuse at home; psychological abuse derived from fears that minors suffers, and the safety that the family must provide. Adaptability to the confinement situation and the fact of declaring cases of abuse are mediated by the role of parents, teachers and relatives.

RESUMEN Introducción: El confinamiento que soportan los niños por la COVID-19 favorece el maltrato infantil. Objetivos: Describir diferentes formas de maltrato infantil que pudieran ocurrir durante el confinamiento debido a la COVID-19. Métodos: La investigación se realizó entre marzo-junio de 2020. Se utilizaron como fuente de información primaria: libros, revistas científicas y tesis y como fuente secundaría: las bases de datos Scielo, Redalyc y documentos de la UNICEF y la UNESCO. Los términos y palabras clave empleados en la búsqueda fueron: familia, maltrato infantil, cuarentena, COVID-19. Resultados: Se define el concepto de maltrato y los factores de riesgo involucrados. Se alude al maltrato físico, por abandono, por abuso sexual, por poder y maltrato psicológico. Se relacionan las reacciones psicológicas que pueden presentar los niños que han sufrido impacto por confinamiento. Se trata la importancia de la detección del maltrato infantil y se brindan orientaciones a los padres. Consideraciones finales: El estado de alerta generado por la COVID-19 ha implantado nuevos estresores que pueden provocar maltrato en la población infantil, como; violencia en la crianza como forma de maltrato físico, las prácticas de abandono aun compartiendo la misma vivienda, el abuso sexual infantil y juvenil en las viviendas; el maltrato psicológico derivado de los temores que sufren los menores y la seguridad que le debe brindar la familia. La adaptación a la situación de confinamiento y declarar casos de maltrato están mediados por el papel de los padres, maestros y familiares.

ABSTRACT Introduction: In the early detection of development problems, it is important to use screening instruments. Objective: To describe the design of an instrument for the screening of psychomotor development's problems in children under six years old. Methods: Development research conducted in Havana, in healthy children under six years old (n= 1 333). The design of instrument was based on the estimation of the ages of compliance related to a set of development guidelines. The 25th, 50th, 75th and 90th percentiles (± 95% CI) of the compliance age of 80 psychomotor development patterns were estimated by means of a logistic regression with inverse transformation. The 50th percentile was compared with that of other similar tests. The instrument was designed with a graphical method with Microsoft Excel 2010 program. Results: All percentiles were estimated in 93.8% of the selected guidelines; in three of them it was not possible to obtain the 25th percentile, the 50th or both, and in two cases they were fulfilled by all the children, so their behavior was not according to a "maturational" model. In the comparisons with respect to foreign tests, the patterns fulfilled at similar and advanced ages prevailed. Conclusions: The instrument designed is a useful tool for the investigation of psychomotor development problems in early childhood, both in care practice and epidemiological studies, and their application in these scenarios contributes to raising the quality of pediatric care.

RESUMEN Introducción: En la detección temprana de los problemas del desarrollo resulta importante emplear instrumentos de pesquisa. Objetivo: Describir el diseño de un instrumento para la pesquisa de los problemas del desarrollo psicomotor en niños menores de seis años. Métodos: Investigación de desarrollo realizada en La Habana, en niños sanos menores de seis años (n=1 333). El instrumento se diseñó a partir de la estimación de las edades de cumplimiento de un conjunto de pautas de desarrollo. Se estimaron los percentiles 25, 50, 75 y 90 (± IC95 %) de la edad de cumplimiento de 80 pautas del desarrollo psicomotor mediante una regresión logística con transformación inversa. Se comparó el percentil 50 con el de las pautas de otras pruebas similares. El instrumento se diseñó con un método gráfico con el programa Microsoft Excel 2010. Resultados: Se estimaron todos los percentiles en 93,8 % de las pautas seleccionadas; en tres de ellas no fue posible obtener el percentil 25, el 50 o ambos y en dos casos fueron cumplidas por todos los niños, por lo que su comportamiento no fue acorde a un modelo “madurativo”. En las comparaciones respecto a pruebas foráneas predominaron las pautas cumplidas a edades similares y adelantadas. Conclusiones: El instrumento diseñado constituye una herramienta útil para la pesquisa de los problemas del desarrollo psicomotor en la primera infancia, tanto en la práctica asistencial como en estudios epidemiológicos. Su aplicación en estos escenarios contribuye a elevar la calidad de la atención pediátrica.

ABSTRACT Growth and development is considered the best positive indicator of children’s quality of life and well-being. Studies have been carried out in Cuba since the early 20th century and large scale, periodic anthropometric surveys have been regularly conducted by its National Health System to chart modifications in growth patterns of children and adolescents. These surveys have produced national references for the anthropometric indicators most commonly applied in individual assessment of the health and nutritional status of children and adolescents in health care settings. These have also provided data for estimating the magnitude and characteristics of secular growth trends, and for comparing growth of Cuban children with that of children in other countries and with WHO’s proposed growth standards. The data have also served as evidence of persisting social gradients. The most important results include, as positive data, the positive secular trend in school-aged children’s growth of 9.7 cm between 1919 and 2005, with an average increase of 1.1 cm per decade, and, in preschool children, 1.9 and 1.8 cm in boys and girls, respectively, between 1972 and 2015. More recent studies have detected unfavorable changes associated with a marked increase in adiposity and, therefore, in the prevalence of excess weight and obesity. Another interesting result is the gradual movement toward WHO height-for-age standards in preschool children in Havana, verified in surveys conducted in 2005 and 2015.

ABSTRACT Introduction: The application of screening tests in the health controls of children allows the early detection of psychomotor development’s problems. Objective: To describe the design and methods used to obtain an instrument for the detection of psychomotor developmental problems in children under six years old. Methods: A development research was carried out between 2014 and 2018, in which a stratified, three-phase and equiprobabilistic sample design was applied by age group and sex. It included nine health areas (polyclinics) in the same number of municipalities and 256 Family doctor-and-nurse’s offices. The inclusion criteria were: children classified as healthy, between 15 days and 6.5 years, with permanent residence in the care area of the selected family doctor-and-nurse’s offices and with the consent of parents or guardians; those with acute diseases at the time of evaluation were excluded. Results: 80 developmental guidelines were selected, and those were distributed in 4 areas and 25 age groups. A total of 1 333 children were studied representing the 96.8 % of the estimated sample. On average, 53 children were evaluated by age group; the average of guidelines evaluated per child was 22. The level of maternal education was high. Conclusions: The design and methods used constitute a reliable base with the purpose of obtaining a valid instrument for the research of psychomotor development’s problems in children under six years, which also it allows obtaining useful information from the assistance and epidemiological point of view.

The first 1000 days of life constitute a short and exceptionally important period when the foundation is established for children’s growth, development and lifelong health. Cuba has a comprehensive care system for this population that aims to promote the best start in life so that children can reach their highest development potential. This is carried out through the national public health and education systems and also includes elements of health protection, prevention of harm and disease and social welfare for children. Cuba’s infant mortality rate has remained <5 deaths per 1000 live births for 10 consecutive years, and in 2017 reached 4 per 1000, the lowest rate to date. The mortality rate for children aged <5 years in 2017 was 5.5 per 1000 live births, with a survival rate of 99.5%; low birth weight was 5.1% and vaccination coverage >95%. Among children aged 1 year in Cuba’s Educate Your Child program in 2014, >90% met age-specific indicators in all four developmental domains (intellectual, motor, socioaffective and language). Cuba has universal coverage for antenatal care and, in 2017, 99.9% of births occurred in health institutions. All working mothers receive paid antenatal leave from 34 weeks of gestation, continued through the child’s first year, to facilitate breastfeeding and child care. In 2018, the Cuban government allocated 27% of its national budget to health and social welfare and 21% to education.

ABSTRACT In Cuba, maternal and child health care is based on the priority granted by the State, the implementation of the National Maternal and Child Health Program and the guarantee of equitable access to health services. This article describes the Cuban experience in this field, as well as its main achievements, challenges, and lessons learned. Among the most relevant results up to 2015 are the reduction of infant mortality rate and under-five mortality rate to 4.3 and 5.7 deaths per 1 000 live births, respectively; 5-year survival of 99.4%; more than 10 prenatal check-ups per delivery; 5.3% of low birth weight; 99.9% of institutional births; and being the first country to validate the elimination of mother-to-child transmission of HIV/AIDS and congenital syphilis. The main challenges are to increase the rate of exclusive breastfeeding; to reduce anemia due to iron deficiency in children and pregnant women; to reduce overweight in children; to prevent accidents; and to reduce maternal mortality, adolescent fertility rate, and voluntary abortion. Among the lessons learned are the priority given by the State to health, the programmatic management of maternal and child care, the guarantee of universal coverage, the systematic collection of information for decision-making, the integration of sectors and social participation in health. Sustaining and improving the results achieved will contribute to the fulfillment of the Sustainable Development Agenda for 2030.

ABSTRACT INTRODUCTION Acute respiratory distress syndrome is a complex heterogeneous disorder with low incidence but high case fatality in children. Treatment with pulmonary surfactants is a possible option. Surfacen, a Cuban exogenous pulmonary surfactant, has been proven safe and effective in premature newborns with hyaline membrane disease, but evidence regarding its efficacy in older children is still inconclusive. OBJECTIVE Determine Surfacen’s efficacy in improving oxygenation and increasing survival in children with acute respiratory distress syndrome. METHODS A multicenter (five pediatric intensive care units in four provinces), open-label, controlled, randomized phase III clinical trial with two treatment groups was conducted from November 2009 through August 2013, with 19 girls and 23 boys aged 1 month to 18 years. The experimental group (20 patients) received conventional treatment (oxygenation and mechanical ventilation) plus intratracheal instillation of Surfacen (100 mg/4 mL) every eight hours for three days. The control group (22 patients) received only conventional treatment. The primary dependent outcome was patient vital status (alive or deceased) 28 days after study enrollment. Other variables and outcomes analyzed were age, sex, ARDS presentation, Kirby index (arterial oxygen tension over inspired oxygen fraction), oxygenation index, static lung compliance, transcutaneous oxygen saturation, radiographic course, mechanical ventilation time and length of stay in neonatal intensive care. Statistical tests used were the chi-square test and Fisher exact test. RESULTS On day 28, there was 80% survival in the experimental group versus 38.1% in the control group. There were significant differences between the experimental and the control group in Kirby index, oxygenation index, static lung compliance and radiographic course, all favoring the experimental group. For every 2.38 patients treated in total, there was one additional survivor in the experimental group. CONCLUSIONS When combined with conventional therapy in the regimen employed, Surfacen improves oxygenation and increases survival in children with ARDS.
