Objetivo. Describir el comportamiento sexual y el uso de anticonceptivos en adolescentes escolarizados. Material y métodos. Encuesta representativa nacional en escuelas de educación media superior en México, realizada en 2014. Modelos logísticos identifican factores asociados al uso de anticonceptivos y a necesidades insatisfechas de anticoncepción (NIA). Resultados. Entre los hombres, no emplear anticonceptivos en la última relación sexual se asocia con la no utilización de éstos durante el debut sexual (RM=11.5;IC95% 5.6-23.4) y desconocer anticonceptivos efectivos (RM=2.4; IC95% 1.04-5.5). Entre las mujeres, no emplear anticonceptivos se asocia con el no uso de éstos durante el debut sexual (RM=4.5; IC95% 2.3-8.4) y la falta de autoeficacia en el uso/negociación del condón (RM=3.1; IC95% 1.18.2). Las NIA se asocian con baja autoeficacia respecto al uso/negociación del condón (RM=3.5; IC95% 1.3-9.4), no usar anticonceptivos en el debut sexual (RM=9.0; IC95% 2.5-32.4) y usar alcohol o drogas en relaciones sexuales (RM=3.0;IC95% 1.1-8.1). Conclusiones. Se requieren estrategias que garanticen el uso de anticonceptivos desde el debut sexual y que promuevan la autoeficacia y las prácticas seguras entre los adolescentes 

Objective. To identify and characterize Aedes aegypti’s AAEL006536 gene proximal upstream cis-regulatory sequences activated by dengue virus infection. Materials and methods. A. aegypti Rockefeller strain mosquitoes were blood fed or infected with dengue virus 2. Open chromatinprofiling was then carried out in pools of midguts from each group of mosquitoes. Results. The proximal upstream region does not contain open chromatin sites in the midguts of blood-fed mosquitoes as detected by FAIRE-qPCR. In contrast, two cis-regulatory sites were identified in the same upstream region of dengue virus-infected mosquito midguts. The distal sequence contains STAT-, REL- and C/EBP-type transcription factor binding sites. Conclusion. The activation of two proximal cis-regulatory sequences, induced by dengue virus infection, is mediated by chromatin remodeling mechanisms. Binding sites suggest a dengue virus infectioninduced participation of immunity transcription factors in the up-regulation of this gene. This suggests the participation of the AAEL006536 gene in the mosquito’s antiviral innate immune response.

Señor editor: La Organización Mundial de la Salud (OMS) reporta que Lima es la segunda ciudad con mayor contaminación atmosférica en Latinoamérica, con un valor promedio anual de material particulado (PM 2.5) de 48 μg/m3.1 Asimismo, se estima que ocurrieron 4 239 muertes atribuiblesa la contaminación del aire en Perú durante 2012.2 Por ello, es importante generar evidencias destinadas a reducir la magnitud e impacto de la contaminación atmosférica.

 Señor editor: He leído con gran interés un artículo publicado recientemente en Salud Pública de México, que brinda resultados interesantes acerca de la satisfacción con la vida, victimización y percepción de seguridad en México. No obstante, es necesario agregar algunos comentarios al artículo porque se utiliza el test de significancia estadística de la hipótesis nula (NHST) para extraer conclusiones. 

Señor editor: Tradicionalmente, en la construcción social en torno a la sordera, prevalece la concepción médica, vinculada con la idea de normalidad, basada en un diagnóstico médico, legitimada por un discurso que promueve un saber y en la cual la sordera requiere una rehabilitación...

Objectives. To report the prevalence of severe functional difficulties and disability (SFD) in a nationally representative sample of children ages 5 to 17 in Mexico, to identify factors associated with SFD, and population profiles predictive of SFD. Materials and methods. Using data from theNational Survey on Children and Women we estimated prevalence and 95% confidence intervals of SFD and risk factors. We fitted bivariate and multivariate logistic regression models. We then examined which combinations of the sociodemographic factors best predicted SFD. Results. The prevalence of SFD was 11.2%. The most prevalent SFD were on the socioemotional dimension (8.3%). The associated risk factors in the three dimensions were: living in a poor household, being a boy, having a mother with basic education or less, and non-indigenous background or living in an urban area. Conclusions. Identifying groups of the population at higher risk for SFD provides useful information for targeted intervention implementation.

The activities concerning mental health care of psychiatric disorders during more than 50 years of service (1966-2016) at the Children’s Psychiatric Hospital “Dr. Juan N. Navarro”(HPI), as well as the progressive development of teaching and research, have contributed to its positioning as a leading institution in medical care of high specialization. This has been possible through the training of human resources that focus the quality of care to the children and their families. The hospital has progressed towards diagnostic and therapeutic care of outpatients through the creation of specialized clinics (emotions, behavior, development, adolescence, among others) and the development of more actualized and integral therapeutic programs (behavioral psychotherapy, cognitive behavioral, psychodynamic; individual, group, family, etc.). In the field of education, the hospital has been the most important institution in the training of child psychiatrists in Mexico and its recognition as a research interdisciplinary center has grown.

Today, there is evidence that shows that children and adolescents can experience developmental problems and psychiatric disorders. This was possible because of two main reasons, the evolution of the concept of infancy and the progress made in medical and psychiatric diagnostic classification. This manuscript offers a glance to early psychiatric attention in Mexico, particularly the care processes provided to 36 children and adolescents under twenty, admitted in the mental asylum La Castañeda, during the first half of the XX century. Admission causes, length of stay, diagnosis, treatment and discharge motives, are some of the aspects described in this study. Finally, it also reflects about the challenge it is for a child psychiatric hospital nowadays, with such a history, to become an innovative institution able to claim a place in the medical field in favor of those minors that can barely defend themselves.

Objective. To report prevalence of severe child functional difficulties and disability (CFD) in a nationally representative sample of 2 to 17 year-old children in Mexico and describe the inequities faced by children with CFD in relation to a set of Sustainable Development Goals (SDG)-related outcomes. Materials and methods. Using data from the National Survey of Children and Women (ENIM 2015) we estimate prevalence with 95% confidence intervals for the selected indicators. We use chi-square test and confidence intervals inspection to report significant differences between children with and without CFD. Results. 8% of children present at least one CFD. CFD is associated with higher prevalence of underweight and child labor and lower prevalence of adequate early child development. Conclusion. Children with CFD present worst outcomes and require targeted efforts to ensure they meet health and wellbeing targets in the frame of the SDGs.

Al hablar del abordaje de salud pública al uso de la marihuana se soslaya la complejidad de la protección a la población a través de intervenciones regulatorias rigurosas. Considerando la experiencia de gobiernos donde ya existen estas prácticas, se introduce la regulación como una función esencial de la salud pública, haciendo explícitos siete propósitos para el control de la marihuana. Se detallan luego los elementos técnicos, de capacidad institucional (incluyendo la capacidad técnica y financiera) y de gobernanza que deben cumplirse para cualquier regulación rigurosa de su uso. Se señala la dificultad de regular sustancias psicoactivas considerando que la capacidad de control de otras actualmente legales se ha traducido en su creciente consumo. Se expone también que no debe minimizarse la necesidad del fortalecimiento institucional y gobernanza de la autoridad regulatoria para la regulación efectiva de la marihuana.
