ABSTRACT

RESUMEN Objetivos La escala motora infantil de Alberta (escala de Alberta en el texto) es utilizada a nivel mundial para evaluar el desarrollo motor en niños menores de 18 meses tanto pretermino como a término. En Colombia la herramienta es utilizada, pero hay poca información sobre los resultados que arroja. El objetivo del estudio fue caracterizar a una cohorte retrospectiva de niños menores de un año según la escala de Alberta para generar información sobre los resultados de la aplicación de esta en población colombiana atendida en un hospital de cuarto nivel. Métodos Estudio descriptivo, retrospectivo, transversal, donde se evaluaron las historias clínicas de 411 niños con edad corregida entre 0 y 12 meses de edad y antecedentes de edad gestacional de menos de 40 semanas, a todos los niños se les aplico la escala de Alberta entre 2010 y 2016 y los puntajes según esta se analizaron estadísticamente en forma descriptiva. Resultados La mayoría de los pacientes fueron clasificados por la escala como "desarrollo normal" como se esperaría por sus antecedentes, los niños de nuestra muestra presentan puntajes inferiores a los de la muestra original de Canadá en todas las edades. Conclusiones La escala se mostró útil en el tamizaje del niño normal, sin embargo, los pacientes presentaron menores puntajes al ser evaluados por la escala que en el estudio original, se genera evidencia sobre la necesidad de validar la escala en Colombia y generar curvas de referencia para esta.(AU)


ABSTRACT Objectives The Alberta Infant Motor Scale is used worldwide to assess motor development in children under 18 months of age, both preterm and full-term. In Colombia, the scale is used, but there is little information on the results it yields. The objective of this study was to characterize a retrospective cohort of children under one year of age according to the Alberta scale to generate information about the results of its application in a Colombian population treated at a highly specialized hospital. Methods Descriptive, retrospective, cross-sectional study, in which the medical records of 411 children with corrected age between 0 and 12 months and a history of gestational age less than 40 weeks were evaluated. The Alberta scale was applied to all children between 2010 and 2016, and scores were analyzed statistically in a descriptive form. Results Most patients were classified by the scale as "normal development" as would be expected based on their medical history. The children in our sample had lower scores than those of the original Canadian sample at all ages. Conclusions The scale was useful for screening normal children; however, the patients had lower scores when they were evaluated by the scale than in the original study, thus making evident the need to validate the scale in Colombia and generate reference curves.(AU)


RESUMO: Objetivos A Escala Motora Infantil de Alberta (escala Alberta no texto) é usada globalmente para avaliar o desenvolvimento motor em crianças menores de 18 meses, pré-termo e termo. Na Colômbia, a ferramenta é usada, mas há pouca informação sobre os resultados mostrados. O objetivo do estudo foi caracterizar uma coorte retrospectiva de crianças menores de um ano, de acordo com a escala de Alberta, para gerar informações sobre os resultados de sua aplicação na população colombiana atendida em um hospital de quarto nível. Métodos Estudo descritivo, retrospectivo, transversal, onde foram avaliados os prontuários de 411 crianças com idade corrigida entre 0 e 12 meses e histórico de idade gestacional inferior a 40 semanas, a escala de Alberta foi aplicada a todas as crianças entre 2010 e 2016 e as pontuações correspondentes foram analisadas estatisticamente de forma descritiva. Resultados A maioria dos pacientes foi classificada pela escala como "desenvolvimento normal", como seria de esperar em sua história; as crianças de nossa amostra tiveram escores mais baixos do que a amostra canadense original em todas as idades. Conclusões A escala foi útil na triagem da criança normal; no entanto, os pacientes tiveram escores mais baixos quando avaliados pela escala do que no estudo original; foram geradas evidências sobre a necessidade de validar a escala na Colômbia e gerar curvas de referência.(AU)

ABSTRACT

ABSTRACT Objective This cross sectional study intended to evaluate two bedside tests (Neuropad and VibraTip) as screening tools for distal symmetrical polyneuropathy (DSPN) in Latin American patients with type 2 diabetes mellitus (T2D). Subjects and methods Ninety-three Colombian patients diagnosed with T2D were recruited. Anthropometric variables, glycemic control parameters, lipid profile and renal function were assessed for each patient. DSPN was defined by a Michigan Neuropathy Screening Instrument (MNSI) clinical score greater than 2. Both Neuropad and Vibratip tests were applied to each patient. Contingency analyses were performed to evaluate the diagnostic power of both tools. Results The prevalence of DSPN determined clinically by MNSI was 25.8%. DSPN in these patients was associated with age, worsening renal function, and insulin treatment. The sensitivity and specificity of the Neuropad test for DSPN was 66.6% and 63% respectively. Its negative predictive value (NPV) was 84.6%. The VibraTip test exhibited a sensitivity of 54.1% and specificity of 91.3%, with a NPV of 85.1%. Conclusion Neuropad and VibraTip are reliable screening tools for DSPN in Latin American population. VibraTip presents a considerable diagnostic power for DSPN in this population. Further studies regarding the cost-effectiveness of these tools in clinical practice are needed.

ABSTRACT

Introdução: Esta pesquisa aborda o desenvolvimento de um sistema neurodifuso para auxiliar no diagnóstico de doenças epilépticas (SNDDDE). Sistemas neurodifusos representam o tipo mais comum de inteligência artificial na medicina. O sistema neurodifuso contém conhecimento médico representado na forma de regras, unindo a força de dois paradigmas: redes neurais artificiais e lógica difusa. Objetivo: O maior interesse da pesquisa é examinar a aplicabilidade das operações aritméticas difusas t-normas e tconormas, implementadas através de neurônios difusos. Resultados: Os resultados mostram que as operações aritméticas difusas Soma/Produto de Einstein E/OU implementadas com o neurônio difuso proposto por Kwan-Cai obtiveram os melhores índices de acertos do sistema quando comparadas com as operações aritméticas padrões máx/mín.


Background: This research approaches the development of a neuro-fuzzy system to support the diagnosis of epileptic diseases (NFSDED). Neuro-fuzzy systems are the most common type of artificial intelligence in medicine. The neuro-fuzzy system contains medical knowledge represented by rules, gathering the strength of two paradigms: artificial neural networks and fuzzy logic. Objective: The main interest of the research is to examine the applicability of the t-norms and t-conorms fuzzy arithmetical operations, implemented by fuzzy neurons. Results: Show that the arithmetical operations of Einstein's Sum/Product AND/OR implemented with the fuzzy neuron proposed by Kwan-Cai obtained the highest rates of system hits, when compared to the min/max arithmetical operations.
