ABSTRACT

Objetivo. Identificar el grupo poblacional en el que se concentra el incremento de sífilis ocurrido durante los últimos años. Material y métodos. A partir de información obtenida de los Anuarios de Morbilidad de la Secretaría de Salud, se conformaron diversas bases de datos con información desagregada por sexo, grupo de edad y entidad federativa durante el periodo de 2003 a 2013. Mediante análisis de regresión lineal, se estimó el incremento con intervalos de confianza a 95%; se evaluaron los cambios a través del tiempo en los diversos grupos poblacionales analizados. Resultados. A partir de 2010 hay un incremento de 0.67 casos por 100000 habitantes (IC95% 0.30-1.04) entre los hombres, que se concentra en individuos de 20 a 24 y de 25 a 44 años. Las mayores incidencias de sífilis adquirida se reportaron en los dos últimos años: 2012 y 2013; este último año registró una incidencia 1.85 veces mayor a la reportada en el año 2003. Entidades como Aguascalientes, Distrito Federal, Durango, México, Oaxaca, Puebla, Quintana Roo, Yucatán y Zacatecas reportaron incrementos de sífilis adquirida durante el periodo de estudio. Conclusión. La sífilis adquirida aparentemente está reemergiendo en México entre hombres jóvenes, incremento que no es homogéneo en el país, por lo que es necesario focalizar medidas de intervención para esta infección de transmisión sexual.


Objective. To identify the population group in which syphilis increase was concentrated. Materials and methods. The information was collected from the Mexico health statistical yearbooks. The information disaggregated by sex, age group and state during the period 2003 to 2013 was used to form different databases. Linear regression analysis with confidence interval at 95% was used to evaluate changes over time in different population groups. Results. An increase of 0.67 cases per 100000 population (95%CI 0.30-1.04) in men was detected from 2010. The increase was concentrated in each group of 20-24 and 25-44. The highest incidence of acquired syphilis was reported in the last two years: 2012 and 2013. The last year reported a 1.85 times higher incidence than reported in 2003. Aguascalientes, Distrito Federal, Durango, Mexico, Oaxaca, Puebla, Quintana Roo, Yucatan and Zacatecas reported that syphilis increased during the study period. Conclusion. Acquired syphilis may be reemerging in our country among young men; this increase is not uniform across the country, it is necessary to focus intervention measures for this sexually transmitted infection.

ABSTRACT

Objective. In 2009, 4 749 rapid HIV tests were run in Morelos, Mexico, despite lacking evidence on their results. This article seeks to analyze how public health organization relates to utility of rapid HIV test among healthcare users. Materials and methods. Joint study: comparison of differences in applied test and positive results for each group with the Bonferroni statistical tool, observational study in 34 health subsystems, and 11 interviews with public healthcare users. Results. Each subsystem processes influenced the use and usefulness of screening; for instance, primary care centers test only pregnant women and exclude men who have sex with men (MSM). That group shows significant differences (p<0.007) in the HIV-positive test with respect to other groups. Conclusions. Despite the availability of rapid detection tests and epidemiological evidence, the way public health services are organized impedes an efficient diagnosis in the group with higher risk, namely MSM. The distribution of rapid HIV tests was guided by stigmatization.


Objetivo. En 2009, 4 749 pruebas rápidas de detección de VIH fueron aplicadas en Morelos, México, sin evidencias de resultados. Se hace necesario analizar la distribución de estas pruebas y las consecuencias que la organización de los servicios de salud tuvo para el diagnóstico del VIH en las poblaciones clave. Material y métodos. Estudio mixto: comparación de diferencias en pruebas aplicadas y casos diagnosticados en grupos mediante la técnica de Bonferroni, observaciones en 34 subsistemas de salud y 11 entrevistas a usuarios. Resultados. Los procesos de cada subsistema incidieron en la utilización y utilidad del tamizaje: se focalizó en mujeres embarazadas y se excluyó a grupos en mayor riesgo (p<0.007) en hombres que tienen sexo con otros hombres (HSH). Conclusiones. A pesar de la disponibilidad de las pruebas y de información epidemiológica, la organización de los servicios impidió una mayor captación de HSH. La estigmatización influyó en las formas de distribuirlas.

ABSTRACT

Objectives: To determine the prevalence of HPV and the risky sexual behaviors associated to it in a sample of male college students, taking into account genotype and viral load. Methods: From 2002 to 2003, male students from the Autonomous University of Morelos State completed a questionnaire and provided self-collected genital samples to detect and quantify HPV. We performed a bivariate and a multivariate logistic regression analysis to identify correlates associated with the infection and to assess the viral load as a function of the viral infecting type. The fragments of β-globin gene and L1 of HPV, were amplified, purified and cloned, to evaluate viral load. Results: Among 253 subjects, HPV prevalence was 19.4%, and HPV16 was the most common subtype. History of STIs (OR = 4.8; 95% CI 1.2–18.9), contraceptive pill use by female partner (OR = 2.6; 95% CI 1.1–6.3) and exchanging sex for money (OR = 4.9; 95% CI 1.2–20) were associated to the HPV infection. HPV16 viral load was 7.8 copies (HPV/beta-globin) compared to 0.9 copies for other HPV types. Discussion: HPV16 displayed the highest viral load, and it was the most prevalent. It was found that using contraceptive pills by female partners was associated with HPV infection. .
