ABSTRACT

El objetivo del presente trabajo fue describir la tasa de descuento sexual y evaluar la relación entre el autorreporte de conductas sexuales arriesgadas (csa) y el descuento sexual en una muestra de adultos jóvenes en Colombia. Para esto, se realizó una investigación no experimental de corte transversal y correlacional. Ciento treinta y seis participantes fueron sometidos a un cuestionario de autorreporte de conductas de riesgo sexual, a la tarea de descuento sexual (sddt) y al cuestionario de elección monetaria (mcq). Los análisis de la curva de descuento sexual demuestran que el valor de la opción de tener sexo seguro disminuye con el in-cremento en la demora en la obtención de un condón (i. e., descuento sexual). Adicionalmente, se observa que el grado de descuento sexual está asociado con csa, como el número de parejas sexuales y el número de relaciones sexuales en los últimos tres meses, y que hay una diferencia en el patrón de descuento sexual entre hombres y mujeres.


The goal of this study was to describe the rate of sexual discounting and its relation with the self-report of sexual risk behavior in a sample of young adults from Colombia. To achieve this goal, a correlational cross-sectional non-experimental study was done. One hundred thirty six young adult participants responded to a sexual risk behavior self-report questionnaire, a sexual delay discounting task (sddt), and a monetary choice questionnaire (mcq). The results suggest that the value of the safe sex option decreases with the delay to obtain a condom (i. e., sexual discounting). Additionally, it was observed that the sexual discounting rate was associated with the self-report of sexual risk behavior, like, the number of sexual partners and sexual encounters in the last three months. It was also observed a different pattern of sexual discounting between men and women


O objetivo deste estudo foi descrever a taxa de desconto sexual e avaliar a relação entre o autorrelato de com-portamentos sexuais de risco (csr) e o desconto sexual em uma amostra de jovens adultos na Colômbia. Para isso, foi realizada uma investigação não experimental, transversal e correlacional. 136 participantes foram submetidos a um questionário de comportamentos se-xuais de risco autorreferidos, à tarefa de desconto sexual (sddt) e ao questionário de escolha monetária (mcq). As análises da curva de desconto sexual mostram que o valor da opção de praticar sexo mais seguro diminui com o aumento do atraso na obtenção do preservativo (ou seja, desconto sexual). Adicionalmente, observa-se que o grau de desconto sexual está associado à csr, assim como o número de parceiros sexuais e o número de relações sexuais nos últimos 3 meses, e que existe uma diferença no padrão de desconto sexual entre homens e mulheres.

ABSTRACT

Abstract Coexistence between thyroid cancer and hyperthyroidism is rare, and most of the nodular lesions from which a malignant tumor is documented in this group of patients correspond to cold nodules. Justified by the increasing number of reports in the literature about malignant tumors diagnosed from hot nodules, a systematic review was carried out to determine possible factors associated with the diagnosis of thyroid cancer from hot nodules in patients with hyperthyroidism. The results suggest that the clinical diagnosis of toxic nodular goiter, nodular lesions of diameter > 10 mm and a histological type compatible with a follicular carcinoma, are factors that on their own increase the risk of making the diagnosis of cancer from a hot nodule.


Resumen La coexistencia entre cáncer de tiroides e hipertiroidismo es infrecuente, y la mayoría de las lesiones nodulares a partir de las cuales se documenta un tumor maligno en este grupo de pacientes corresponden a nódulos fríos. Justificado en el creciente número de reportes en la literatura acerca de tumores malignos diagnosticados a partir de nódulos calientes, se realizó una revisión sistemática que tuvo como objetivo determinar los posibles factores asociados con el diagnóstico de cáncer de tiroides a partir de nódulos calientes en pacientes con hipertiroidismo. Los resultados sugieren que el diagnóstico clínico de bocio nodular tóxico, lesiones nodulares de diámetro mayor de 10 mm y tipo histológico compatible con carcinoma folicular, son factores que aumentan por sí solos el riesgo de realizar el diagnóstico de cáncer a partir de un nódulo caliente.

ABSTRACT

INTRODUCTION: The hypothesis of an association between papillary thyroid carcinoma (PTC) and chronic lymphocytic thyroiditis (CLT) continues to generate debate. Retrospective studies suggest that there is a greater probability of diagnosing a PTC in surgical specimens with CLT; however, prospective studies suggest that there is no true increase in risk. METHODS: An analytical, cross-section measurement and retrospective study was carried out considering gender, age and diagnosis of CLT and PTC in surgical specimens. A binary logistic regression model was proposed to predict the probability of carrying out the diagnosis of PTC based on the diagnosis of CLT, gender and age. RESULTS: The study population consisted of 1136 patients, 1047 (92.2%) women and 89 (7.8%) men, with an average age of 47.5±14.3 years. The prevalence of CLT and PTC was 14.9% and 16.1% respectively. Coexistence between PTC and CLT was found in 44 patients, corresponding to 3.9% of the population. Our logistic regression model suggests that the probability of diagnosing PTC in surgical specimens of male patients under 40 years old and with CLT is 53.8%. CONCLUSIONS: We suggest that there is a greater probability of diagnosing PTC in surgical specimens with confirmatory histological data for CLT; in addition, in males under 40 years old this probability increases


INTRODUCCIÓN: La hipótesis que sugiere una asociación entre el cáncer papilar de tiroides (PTC, por sus siglas en inglés) y la tiroiditis linfocítica crónica (CLT, por sus siglas en inglés) sigue generando debate. Los estudios retrospectivos sugieren que existe una mayor probabilidad de realizar un diagnóstico de PTC en las muestras quirúrgicas de CLT. Los estudios prospectivos sugieren que no existe un incremento real del riesgo. MÉTODOS: Se realizó un estudio analítico de medición transversal y temporalidad retrospectiva en cuanto a sexo, edad, diagnóstico de CLT y espécimen quirúrgico de PTC. Se propuso un modelo de regresión logística binaria para predecir la probabilidad de realizarse un diagnóstico de PTC basado en el diagnóstico de CLT, sexo y edad. RESULTADOS: La población de estudio consistió en 1.136 pacientes, 1.047 mujeres (92,2%) y 89 varones (7,8%), con una edad media de 47,5 ± 14,3 años. La prevalencia de CLT y PTC fue del 14,9% y 16,1%, respectivamente. La coexistencia de PTC y CLT fue encontrada en 44 pacientes, correspondiente al 3,9% de la población. Nuestro modelo de regresión logística sugiere que la probabilidad de realizar el diagnóstico de PTC en muestras quirúrgicas de pacientes varones con edades inferiores a 40 años y con CLT es del 53,8%. CONCLUSIONES: Sugerimos que existe una mayor probabilidad de diagnosticar PTC en muestras quirúrgicas con datos histológicos confirmatorios de CLT; además, esta probabilidad puede modificarse sobre la base de sexo masculino y edad superior a 40 años

ABSTRACT

Con el objetivo de evaluar la concentración y la morfología de los espermatozoides de la cola del epidídimo de testículos de toros postmortem, obtenidos mediante lavado por flujo retrógrado, se recolectaron al azar 90 testículos, los cuales fueron transportados bajo dos diferentes temperaturas, siguiendo dos protocolos diferentes: Protocolo 1 (35ºC) y Protocolo 2 (25ºC), durante el período abril-julio 2003. El material experimental fue transportado desde el sitio de la recolección hasta el laboratorio, en un lapso comprendido entre 30 y 60 min con un promedio de 45 min. Se realizó histopatología para seleccionar los testículos con 70% o más de tejido funcional para cada protocolo (Protocolo 1: n=13; y Protocolo 2: n=20). Una vez realizado el descarte de aquellos testículos que no cumplieron con esa premisa, se evaluó la concentración espermática y la morfología de los espermatozoides de las colas epididimarias en los testículos seleccionados. La recolección de esos espermatozoides se realizó por lavado retrógrado con TRIS-yema-glicerol, a través del conducto deferente. Se determinó la concentración espermática mediante la cámara de Neubauer, en el fluido espermático y la morfología espermática se determinó en función del porcentaje de espermatozoides normales y de las atipias encontradas, previa tinción con Hema III. Los datos se analizaron mediante estadística descriptiva, y se realizó una prueba de t de Student para comparar muestras independientes. Los resultados obtenidos indican que no hubo diferencia significativas, entre los dos protocolos en la morfología normal, ni el total de atipias. Según este estudio, la temperatura de transporte no afecta la calidad espermática epididimaria.


In this investigation, the concentration and morphology of spermatozoa of the epididymal tail of post mortem bull testicles, obtained by retrograde flushing, were evaluated. The experiment was done from April-June 2003. Ninety testicles were randomly collected and transported to the laboratory, following two different temperature protocols: Protocol 1 (35°C) and Protocol 2 ( 25°C). The testicles were transported from the slaughterhouse (Frogorífico Industrial de Turmero, the State of Aragua, Venezuela) to the laboratory within a time frame of 30-60 min, with an average time of 45 min. For each protocol (Protocol 1, n=13; Protocol 2, n=20), a histopathological study of all samples was performed and those testes with 70% or more of functional tissue were selected. After discarding the testicles which did not comply with the required conditions, the spermatic concentration and morphology of spermatozoa were assessed. Spermatozoa collection was carried out by retrograde flushing using TRIS-egg yolk glycerol medium through the deferent duct. The spermatic concentration was obtained using the Neubauer chamber while the spermatic morphology was estimated by observation of smears stained with Hema III, and comparing the percentage of normal versus abnormal spermatozoa. The data was analyzed by descriptive statistics and the t test was applied to compare two independent samples. The results obtained showed no statistical significant differences between the two protocols, regarding normal morphology and total percentage of abnormal spermatozoa. It is concluded that the two different temperature protocols do not affect the quality of spermatozoa of the epididymal tail.
