Temporary restorative treatment in children and adolescents with amelogenesis imperfecta: Scoping review

Background: Amelogenesis imperfecta (AI) is a group of disorders that affect the enamel of the teeth, either in quality or quantity. This alteration causes sensitivity and is associated with factors that could affect the strength of the adhesive bond of the restorative material. Aim: To review the literature regarding the most used temporary restorative treatment in children and adolescents with AI. Methods: This scoping review aimed to include case reports, literature reviews and original studies that evaluated restorative materials for the teeth of children and adolescents with AI. Editorials, meeting abstracts and letters to the editor were excluded. The following electronic databases were used: Medline (Ovid), PubMed, Ebsco, Scopus (Elsevier) and Web of Science (Thomson Reuters). Manual searches in the reference lists of the included articles were also carried out. Finally, a search in Google Scholar restricted to the first 100 hits was performed. Duplicates were eliminated upon identification. The search covered a period between the years of 2011 and 2016. PRISMA guidelines were used for reporting the review. The evidence ranking was carried out by means of the Oxford criteria. Results: Six articles met the eligibility criteria and were included in this scoping review. Three articles were case reports, one was a review and two were original studies. For the treatment of AI, direct or indirect composite resins were the most commonly used material of choice in the retrieved studies because they demonstrate greater longevity, aesthetics and function compared to the other materials used. Conclusions: Among children and adolescents with AI, the temporary restorative treatment that demonstrated better long-term results in permanent teeth was the direct and indirect composite resins. However, high quality studies should be conducted to confirm the results presented herein

Cognitive Impairment and Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) is a frequent sleep disorder characterized by repetitive interruption of ventilation caused by partial or complete collapse of the upper airway during sleep. OSA is highly prevalent in the world and it has been associated with cardiovascular disease and cognitive impairment in children and adults. The cognitive impairment in individuals with OSA includes deficiencies in attention and constructional abilities, delayed long-term visual and verbal memory, and executive functions. Although, the pathogenesis of cognitive impairment in patients with OSA is complex and remains incompletely understood, several mechanisms, such as hypoxia, inflammation and sleep fragmentation have been proposed. The aim of this chapter is to describe some findings reported in the literature to explain the association between OSA and cognitive impairment

Ser en el arte: caminos de reconocimiento

Esta vivencia investigativa tuvo como propósito generar reflexiones creativas, sentidas y encarnadas en torno a las experiencias de reconocimiento que las personas con dis_capacidad de la Fundación Luna Arte viven en sus recorridos artísticos desde la perspectiva de Axel Honneth. Estas reflexiones, nacen desde los cuerpos metaforizados en los body maps que se enmarcan en la Investigación Basada en las Artes como metodología del estudio. Se concluye principalmente que el disfrute y la participación en la vida artística contribuye a la estima social de esta población y, por ende, al realce de sus capacidades, cualidades y a la valoración de sus aportes dentro de su comunidad

Taxation and cooperativism: the fiscal regime of the non-agricultural cooperatives (CNA) in Cuba

Los sistemas tributarios modernos regulan, para las cooperativas, un conjunto de incentivos fiscales que buscan fundamentalmente impulsar su creación por encima de otros sujetos económicos y motivar la inversión y la creación de fondos sociales. En el caso particular de Cuba, donde impera un sistema económico socialista, la necesidad de incentivar formas de propiedad social por encima del sector privado, cobra aún mayor significación, lo que se reconoce en los Lineamientos de la política económica y social, aprobados en el VI Congreso del Partido Comunista de Cuba, el 18 de abril de 2011 y en el Séptimo Período Ordinario de Sesiones de la VII Legislatura de la Asamblea Nacional del Poder Popular el 1 de agosto de 2011. Es por eso que, además de las tradicionales cooperativas agropecuarias, en el año 2012 se haya aprobado la creación de cooperativas denominadas “no agropecuarias”. Estas cooperativas gozan de un régimen tributario especial, regulado en la Ley No. 113 que se promulgó en ese propio año, liderado por los beneficios recibidos en el impuesto que grava la renta (Impuesto sobre Utilidad Per cápita); sin embargo, el sacrificio fiscal que encierra este tipo de regulaciones no tiene razón de ser, si estas no están encaminadas al desarrollo de esta forma de gestión; lo que en este caso resulta cuestionable, ya que la aprobación de nuevas cooperativas está suspendida y los posibles beneficios no están encaminados a promover la inversión.Modern tax systems regulate, for cooperatives, a set of fiscal incentives that fundamentally seek to promote their creation over other economic subjects and motivate investment and creation of social funds. In the particular case of Cuba, where a socialist economic system prevails, the need to incentivize forms of social property over the private sector, acquires even greater significance, which is recognized in the Guidelines of the economic and social policy, approved in the VI Congress of the Communist Party of Cuba on April 18, 2011 and the Seventh Ordinary Session of the VII Legislature of the National Assembly of the People´s Power on August 1, 2011. That is why, in addition to the traditional agricultural cooperatives, in 2012 the creation of cooperatives called “non- agricultural” was approved. These cooperatives enjoy a special tax regime, regulated by Law No. 113 that was enacted in the same year, led by the benefits received in the tax levied on income (per capita income tax). However, the fiscal sacrifice involved in this type of regulation has no reason to be, if these are not aimed at the development of this form of management, which in this case is questionable, since the approval of new cooperatives is suspended and the Potential benefits are not aimed at promoting investment.Escuela de Estudios CooperativosFac. de Ciencias Económicas y EmpresarialesTRUEpu

Tributación y cooperativismo: el régimen fiscal de las cooperativas no agropecuarias (CNA) en Cuba

Análisis psicométrico de una prueba de física para grado decimo del colegio Nicolás Gómez Dávila – IED

Se muestran los resultados de la investigación para medir la confiabilidad de una prueba de física previamente diseñada y aplicada a los estudiantes del ciclo V del colegio Nicolás Gómez Dávila IED; el análisis de este trabajo se hizo a través de la perspectiva de la teoría clásica de los test y se complementa con la teoría de respuesta al ítem. Lo anterior, como fundamento práctico que permita a la institución educativa utilizar estos análisis y resultados como herramienta de apoyo en el momento de decidir cómo fortalecer los elementos de evaluación del estudiantado. La prueba se aplicó a 60 estudiantes del ciclo V, los cuales correspondían al 100% del público objetivo al que se podía aplicar dicho test; los ítems utilizados fueron tomados de un banco de preguntas. Los resultados de las teorías mencionadas, muestran que el test es confiable y que para mejorar el índice de confiabilidad es necesario eliminar dos ítems, por lo tanto el 87% de los ítems evaluados cumplen con un nivel alto de confiabilidad y se recomienda que la prueba pueda seguir siendo utilizada
