RESUMEN

Resumen El cáncer de mama es el cáncer más frecuente en las mujeres y constituye un problema de salud pública debido a sus altas tasas de morbimortalidad. El diagnóstico se hace a través de estudios rutinarios de histopatología que se complementan con estudios de expresión de receptores hormonales (Receptores de Estrógenos y Progesterona), del factor de crecimiento epidérmico humano 2 (HER2) e índice de proliferación celular (Ki67) para su subtipificación en grupos moleculares (Luminal A, Luminal B, Her2 y triple negativo), los cuales tienen implicaciones pronósticas y terapéuticas diferentes. Globalmente, se ha reportado una alta prevalencia del subtipo Luminal A, predominantemente en Norteamérica, Europa y algunos países latinoamericanos, sin embargo, los reportes en la población colombiana son heterogéneos. El objetivo de esta investigación es establecer un perfil de incidencia de dichos subtipos moleculares en una población del eje cafetero en Colombia. Retrospectivamente se analizaron muestras de 377 pacientes con diagnóstico de cáncer de mama infiltrante, entre los años 2015 a 2018. Los diagnósticos histológicos incluyeron: Carcinomas Ductal infiltrante NOS (339 casos; 89.9 %), lobulillar infiltrante (23 casos; 6.1 %), mucinoso infiltrante (6 casos; 1.5 %), papilar infiltrante (1 caso; 0.2 %) y patrones mixtos: ductal-lobulillar (3 casos; 0.7 %) y ductal con componente mucinoso (5 casos; 1.3 %), de los cuales 56.2 % (212 casos) corresponden a luminal B, 22.2 % (84 casos) a Luminal A, 14.8 % (56 casos) a triple negativo y 6.6 % (25 casos) a HER2. Estos hallazgos contrastan con la prevalencia reportada a nivel mundial. Por lo tanto, en la población del eje cafetero colombiano, se debe considerar este predominio del patrón luminal B al momento de establecer pronóstico y tratamiento por parte del personal médico tratante.

Abstract Breast cancer is the most common cancer in women and constitutes a public health problem due to its high rates of morbidity and mortality. Diagnosis is made through routine histopathology studies that are complemented by expression studies of hormone receptors (Estrogen and Progesterone Receptors), human epidermal growth factor 2 (HER2) and cell proliferation index (Ki67) for their subtyping into molecular groups (Luminal A, Luminal B, Her2 and triple negative), which have different prognostic and therapeutic implications. Globally, a high prevalence of the Luminal A subtype has been reported, predominantly in North America, Europe, and some Latin American countries; however, the reports in the Colombian population are heterogeneous. The objective of this research is to establish an incidence profile of these molecular subtypes in a population of the coffee region in Colombia. In retrospect, samples of 377 patients with a diagnosis of infiltrating breast cancer were analyzed, between the years 2015 and 2018. The histological diagnoses included: NOS infiltrating ductal carcinomas (339 cases; 89.9 %), infiltrating lobular (23 cases; 6.1%), infiltrating mucinous (6 cases; 1.5%), infiltrating papillary (1 case; 0.2%) and mixed patterns: ductal - lobular (3 cases; 0.7%) and ductal with mucinous component (5 cases; 1.3%), of which 56.2% (212 cases) correspond to luminal B, 22.2% (84 cases) to Luminal A, 14.8% (56 cases) to triple negative and 6.6% (25 cases) to HER2. These findings contrast with the prevalence reported worldwide. Therefore, in the population of the Colombian coffee region, this predominance of the luminal pattern B should be considered when establishing prognosis and treatment from medical staff.

RESUMEN

Resumen Introducción: La marihuana es concebida como una droga de bajo riesgo, considerada ilegal en Colombia, si bien es la más consumida por los adolescentes. Objetivo: Describir la prevalencia y examinar los factores asociados al consumo de marihuana durante los últimos 30 días por adolescentes escolarizados de Colombia. Método: Estudio transversal analítico. Muestra constituida por 80.018 adolescentes escolarizados entre 12 y 18 años. Se considera "adolescente consumidor de marihuana", a aquél que declaró haberla consumido durante los últimos treinta días. Se tuvieron en cuenta variables de interés, el sexo, la edad, el tipo de colegio, los episodios de ideación suicida y autolesión deliberada, la existencia de problemas de rendimiento académico y disciplinarios. Se realizó una descripción de la prevalencia de marihuana por cada una de las variables de interés. Se estimaron asociaciones por medio de modelos lineales generalizados, todos los análisis fueron ajustados por el factor de expansión. Resultados: La prevalencia de consumo de marihuana en los últimos 30 días fue del 4,3 % (IC 95 % 4,1 %- 4,6 %). Las mayores prevalencias de consumo se registraron en adolescentes que habían reportado 3 o más veces de ideación suicida en los últimos 12 meses, y en aquellos que acusaron 3 o más veces de autolesión deliberada en los últimos 12 meses (10,4 % y 10,0 %, respectivamente). Se encontró una asociación con todas las variables estudiadas. Conclusiones: Se evidenció una fuerte asociación entre el consumo de marihuana y presencia de episodios de autolesiones deliberadas y episodios de ideación suicida en adolescentes escolarizados.

Summary Introduction: Marijuana is conceived as a low-risk drug, considered illegal in Colombia, and the most consumed by adolescents. Objective: To describe the prevalence and examine the factors associated with marijuana use during the last 30 days by adolescents in school in Colombia. Method: Cross-sectional analytical study. Sample is 80,018 adolescents in school between 12 and 18 years of age. An "adolescent user of marijuana" is one who declared having used it during the last thirty days. Variables of interest were considered: sex, age, type of school, episodes of suicidal ideation and deliberate self-harm, the existence of academic and disciplinary performance problems. A description of the prevalence of marijuana was made for each of the variables of interest. Associations were estimated using generalized linear models, all analyzes were adjusted for the expansion factor. Results: The prevalence of marijuana use in the last 30 days was 4.3% (95% CI 4.1%-4.6%). The highest prevalence of consumption was recorded in adolescents who had reported 3 or more times of suicidal ideation in the last 12 months, and in those who accused 3 or more times of deliberate self-harm in the last 12 months (10.4% and 10. 0%, respectively). An association was found with all the variables studied. Conclusions: A strong association was found between marijuana use and the presence of episodes of deliberate self-harm and episodes of suicidal ideation in school adolescents.

RESUMEN

Introducción: El consumo de marihuana toma un singular interés en el contexto de la universidad y en los universitarios, pues su uso podría ser parte de las relaciones sociales con sus pares. Objetivo: Describir la prevalencia y examinar los factores asociados al consumo de marihuana durante los últimos treinta días en estudiantes universitarios de Colombia durante 2016. Método: Estudio transversal analítico. Se realizó un análisis con 9555 universitarios colombianos. Fue considerado como consumidor de marihuana el universitario que manifestó haberla consumido durante los últimos treinta días. Se tomaron como variables de interés el sexo, la edad, la percepción de la situación económica, los problemas académicos y disciplinarios en la secundaria y las características de control parental. Para el análisis se reportó la prevalencia de la marihuana por cada una de las características estudiadas. Las asociaciones fueron estimadas a través de modelos lineales generalizados, tales análisis se ajustaron por el factor de expansión. Resultados: Se halló que el 9,7 % (IC 95 % 9,1 %- 10,4 %) había consumido marihuana en los últimos treinta días; los hombres (OR 2,23 IC95 % 1,92 - 2,59), aquellos que acusaron no tener control parental sobre los amigos (OR 2,32 IC95 % 1,58- 3,41) y que confesaron haber tenido problemas disciplinarios en la secundaria (OR 3,35 IC95 % 2,67-4,19), mostraron asociación con el consumo de marihuana. Conclusiones: La prevalencia de consumo de marihuana en estudiantes universitarios es elevada con respecto a otros países de la región. Destacan características como la presencia de problemas académicos o disciplinarios en la secundaria, así como un pobre control parental; ellas mostraron que tenían mayor relación con el consumo de marihuana entre los universitarios indagados.

Introduction: The consumption of marijuana takes on a singular interest in the context of the university and university students, because its use could be a part of relationships with their peers. Objective: To describe the prevalence and examine the factors associated with marijuana use during the last thirty days, in university students in Colombia, during the year 2016. Method: Cross-sectional analytical study. An analysis was carried out with 9555 Colombian university students. The university student who stated that he had used it during the last thirty (30) days was considered a marijuana user. The studied variables were sex, age, perception of the economic situation, academic and disciplinary problems in high school, and the characteristics of parental control. For analysis, the prevalence of marijuana was reported for each of the characteristics studied. The associations were estimated through generalized linear models; all analyzes were adjusted by the expansion factor. Results: It was found that 9.7% (95% CI 9.1%-10.4%) had used marijuana in the last thirty days; men (OR 2.23 CI95% 1.92 - 2.59), those who reported not having parental control over friends (OR 2.32 CI95% 1.58-3.41) and who confessed to having had disciplinary problems in high school (OR 3.35 CI95% 2.67-4.19) were associated with marijuana use. Conclusions: The prevalence of marijuana use in university students is high, compared to other countries in the region. They highlight characteristics such as the presence of academic or disciplinary problems in high school, as well as poor parental control; they showed that they had a greater relationship with the use of marijuana among the university students surveyed.

RESUMEN

BACKGROUND: Deliberate self-harm and the consumption of psy- choactive substances are important public health problems among adolescents. AIM: To determine the association of deliberate self-harm with the consumption of psychoactive substances, in school adolescents in Colombia. MATERIAL AND METHODS: A survey about deliberate self harm and psychoactive substance use during the last 12 months was answered by 80 018 adolescents aged between 12 and 18 years. RESULTS: The prevalence of deliberate self-harm in the last 12 months was 14.1%. The use of psychoactive drugs was associated with deliberate self-harm. The greatest association was observed with the use of non-prescription tranquilizers (Odds ratio 4.05 95% confidence intervals 3.42-4.81). CONCLUSIONS: We observed an association between deliberate self-harm and the consumption of different psychoactive substances.

RESUMEN

Teaching models in endoscopy are important tools to minimize risks derived from endoscopic procedures, taking into account that therapeutic endoscopy, also known as surgical endoscopy, has greatly developed during the last decade. This results from the fact that minimally invasive procedures present relevant contributions and promote more comfort to patients. In this context, ex vivo teaching models and virtual simulators are important tools to the safe acquisition of abilities. In this article, the Brazilian Society of Digestive Endoscopy presents and describes its first course of therapeutic ERCP and EUS in models of laboratory teaching.
