ABSTRACT

Introducción: Los ftalatos son disruptores endocrinos usados en la fabricación de múltiples productos de la industria, principalmente plásticos. El periodo fetal representa la principal ventana de vulnerabilidad, y la exposición a ftalatos en esta etapa de vida genera efectos adversos fetales y postnatales. El biomarcador más fiable para medición de ftalatos es la orina. Objetivo: Caracterizar las diferentes fuentes de exposición a disruptores endocrinos y cuantificar la concentración urinaria de ftalatos en gestantes. Materiales y métodos: Estudio transversal, observacional y descriptivo que incluye 400 gestantes que asistieron a control prenatal en las instituciones de salud Génesis y Metrosalud (Medellín-Colombia). Se caracterizaron fuentes de exposición, se recolectó muestras de orina de todas las gestantes, y cuantificó la concentración de ftalatos de 38 mujeres. Resultados: Las medias geométricas de ftalato Di(2-ethylhexyl)phthalate(DEHP), Mono-n-butyl phthalate(MnBP), Mono-2-ethyl-5-hydroxyhexyl phthalate(MEHHP) y Mono-2-ethyl-5-oxohexyl phthalate(MEOHP) fueron 162,72µg/L, 58,5 µg/L, 33,93µg/L y 31,63µg/L respectivamente. Conclusiones: La mayoría de las gestantes evaluadas han estado expuestas a lo largo de su vida a fuentes potenciales de disruptores endocrinos, presentes en químicos domésticos, tabaco y uso frecuente de cosméticos faciales y corporales. Las concentraciones de MnBP, MEHHP y MEOHP en orina de las participantes, fueron superiores a los hallazgos a nivel mundial.


Introduction: Phthalates are endocrine disruptors used in the manufacture of various industrial products, mainly plastics. The fetal period represents the principal window of vulnerability, and the exposure to Phthalates in this stage of life generates adverse fetal and post-natal effects. The most reliable biomarker for the assessment of Phthalates is urine. Objective: To characterize the different exposure sources of endocrine disruptors and quantify the urinary concentration of Phthalates in pregnant women. Materials and methods: A cross-sectional, observational, and descriptive study which included 400 pregnant women who received prenatal care in the Genesis and Metrosalud health institutions (Medellín-Colombia). Exposure sources were characterized and urine samples were collected from all pregnant women and the Phthalate concentration was quantified in 38 women. Results: The geometric measures of Phthalate Di(2-ethylhexyl)phthalate(DEHP), Mono-n-butyl phthalate(MnBP), Mono-2-ethyl-5-hydroxyhexyl phthalate(MEHHP) and Mono-2-ethyl-5-oxohexyl phthalate(MEOHP) were 162.72µg/L, 58.5 µg/L, 33.93µg/L and 31.63µg/L respectively. Conclusions: The majority of pregnant women that were evaluated were exposed to potential sources of endocrine disruptors throughout their life, which are present in household chemicals, tobacco, and frequent use of facial and body cosmetics. The concentrations of MnBP, MEHHP y MEOHP in urine of participants were higher than those found worldwide.

ABSTRACT

INTRODUCTION: Congenital heart diseases are the most common congenital abnormalities in newborns with a prevalence of 1%. Therapeutic and diagnostic cardiac catheterization has revolutionized the treatment of these diseases; however, it can be associated with complications. OBJECTIVE: To describe the incidence and type of complications associated with pediatric cardiac catheterization in a reference center for congenital heart defects. METHODOLOGY: Retrospective observational study, with analytical intention based on records of cardiac catheterization performed on patients with congenital and acquired heart disease. RESULTS: 2,688 records were included for nine consecutive years. 53.9% were men, 21.3% with ages between 2 and 5 years and 20.3% between 6 months and 2 years. 63.5% of the procedures were elective. The prevalence of complications in the first 24 hours after catheterization was 6.7% (4.2% minor and 2.4% major). Early death occurred in 0.8% of the procedures. Factors associated with complications were age at catheterization <28 days (OR 2.18, 95% CI [1.28-3.70]), precatheter oxygen saturation <79% (OR 2.15, 95% CI [1.02-4.53]), use of pre-catheter inotropics (OR 3.00, 95% CI [1.68-5.33]). The variables included in the model explain 38% of the variance of post-cardiac catheterization complications in patients younger than 18 years. DISCUSSION: Cardiac catheterization is associated with major and minor complications including death. The associated factors were less than 28 days, lower oxygen saturation and use of pre-catheter inotropics.


INTRODUCCIÓN: Las cardiopatías congénitas son las anomalías congénitas más comunes en recién nacidos con una prevalencia de 1%. El cateterismo cardíaco diagnóstico y terapéutico ha revolucionado el tratamiento de estas enfermedades, aunque puede acompañarse de complicaciones. OBJETIVO: Describir la incidencia y el tipo de complicaciones vinculadas con el cateterismo cardíaco pediátrico en un centro de referencia para cardiopatías congénitas. MÉTODO: Estudio observacional retrospectivo, con intención analítica a partir de registros de cateterismos cardíacos realizados a pacientes con cardiopatías congénitas y adquiridas. RESULTADOS: Se incluyeron 2,688 registros durante nueve años consecutivos. El 53.9% correspondió a hombres, 21.3% con edades de dos a cinco años y 20.3% de seis meses a dos años. El 63.5% de los procedimientos fue electivo. La prevalencia de complicaciones en las primeras 24 horas posteriores al cateterismo fue de 6.7% (4.2% menores y 2.4% mayores). En el 0.8% de los procedimientos sobrevino la muerte temprana. Los factores relacionados con las complicaciones fueron: edad al momento del cateterismo <28 días (OR, 2.18; IC 95%, 1.28-3.70), saturación de oxígeno antes del cateterismo <79% (OR, 2.15; IC 95%, 1.02-4.53), uso de inotrópicos antes del cateterismo (OR, 3.00; IC 95%, 1.68-5.33). Las variables incluidas en el modelo explican el 38% de la varianza de las complicaciones posteriores al cateterismo cardíaco en pacientes menores de 18 años. CONCLUSIONES: En este estudio, el cateterismo cardíaco se vinculó con complicaciones mayores y menores, incluida la muerte. Los factores adjuntos fueron edad menor de 28 días, menor saturación de oxígeno y uso de inotrópicos antes del cateterismo.
