Resumen Objetivo: Determinar la incidencia de la depresión, así como la tasa de suicidio en México en los últimos años. Materiales y métodos: Análisis observacional mediante bases de datos de acceso abierto sobre casos de depresión y mortalidad en México entre los años 2014-2021; se calculó incidencia y tasa de suicidio a partir de ellos junto a un intervalo de confianza del 95% asumiendo una distribución de Poisson. Resultados: Desde 2014 se observa un aumento en la incidencia de la depresión en México; las proyecciones calculadas muestran que esta tendencia de aumento continuará durante los próximos años. El sexo femenino muestra mayor incidencia, mientras que el grupo de edad más afectado es el superior a 60 años. El estado con mayor incidencia es Durango. Del mismo modo, la tasa de suicidio muestra una tendencia de aumento en los años estudiados. Conclusiones: La depresión es un problema creciente en materia de salud en todo el mundo. En México aún existe mucha desinformación acerca de la prevalencia e incidencia de esta enfermedad, por lo que un diagnóstico temprano podría derivar en una planeación para el eficiente tratamiento del problema en los próximos años.

Abstract Objective: The objective of this study was to determine the incidence of depression as well the suicide rate in Mexico in the past years. Materials and Methods: Observational analysis through open access databases on cases of depression and mortality in Mexico between the years 2014-2021; the incidence and suicide rate were calculated along the 95% confidence interval by assuming a Poisson distribution. Results: The incidence of depression in Mexico has increased since 2014; the calculated incidence in the next years shows that this trend will continue. Females are more affected than men, while the age group most affected is people over 60 years of age. The Mexican state that registers more new cases is Durango. The suicide rate also shows an increasing trend in recent years. Conclusion: Depression is a growing health public problem. The early diagnosis of depression in Mexico is still insubstantial; then, better surveillance of this disease is necessary to properly address the problem.

Abstract: The dengue virus has become an increasingly critical problem for humanity due to its extensive spread. This is transmitted through a vector that sprouts in certain climatic conditions (tropical and subtropical climates). The transmission of the disease can be associated with certain climatic variables that reinforce the outbreak. Data were collected on dengue cases by epidemiological week registered in Loreto-Peru from January 1, 2016, to January 31, 2022. Likewise, data on meteorological variables (maximum and minimum temperature; dry and humid bulb temperature; wind speed and total precipitation in the area). In this study, four Machine learning modeling techniques were considered: Support Vector Machine (SVM), Decision Tree, Random Forest and AdaBoost; and the parameters defined to evaluate the models are: Accuracy, Precision, Recall and F-1. As a result, optimal AUC values were obtained in a range from 0.818 to 0.996 for the SVM, Random Forest and AdaBoost algorithms, likewise, in all weather stations the ROC curve showed good performance for all models, except for the Decision Tree algorithm. As a conclusion for this study, we propose the optimal model to associate dengue cases with climatic conditions is SVM.

ABSTRACT This article approaches Engineering Requirements concepts and proposes the use of cognitive maps as support to the problem identification of the stakeholders during the requirements elicitation process. It presents a case study of the aerospace cluster of São José dos Campos, State of São Paulo. The cognitive map technique was developed to represent the views of the individuals, generating cognitive maps, which, in an aggregated way, express graphically the collective vision to support the decision-making process. Applied to Engineering Requirements, it has revealed the potential to promote the convergence of different points of view on the actual stakeholders’ needs in innovative fashion. This technique has demonstrated effectiveness when approaching the stated requirements early in the development process implemented throughout the life cycle of the system/product.

Background: The objective of the study was to assess the association between TV foods advertisements and the ones consumed by mothers and children, and the body weight of both mother and child, among population from different SES in two Mexican cities. Methods: During June through October 2011 in Tijuana and Tuxtla Gutierrez, two national broadcasted channels were recorded during a period of 5 h in the afternoon on working days. Direct interviews were conducted to explore the foods consumed by mothers and their children from january to july 2012. To identify the difference in the number of hours of TV watching, number of TV sets, and the number of advertisements they recalled, a one-way ANOVA was used. Results: An association was observed between the consumption of advertised foods by mothers and the frequency of broadcasted advertising. It was also observed that there was an association between the hours watching TV and BMI of the mothers and BMI Z-score of their children. Conclusions: There was an association between BMI of the mothers and their children and time spent watching TV. The high exposure to TV food advertisements in Mexico may increase the odds for having childhood obesity.

Antecedentes: El objetivo de este estudio fue valorar la asociación entre los anuncios de alimentos en TV, los alimentos consumidos por las madres y los niños, y el peso corporal de madres y niños entre población con diferentes niveles socioeconómicos. Métodos: De junio a octubre de 2011 en Tijuana y Tuxtla Gutiérrez, se grabaron los programas de dos canales nacionales durante un período de cinco horas, cinco días laborables. Se realizaron entrevistas a las madres de enero a julio de 2012, para explorar los alimentos consumidos por las madres y los niños. Para identificar las diferencias entre el número de horas de TV, el número de unidades de TV, y el número de anuncios que recordaban se realizó análisis de una vía de ANOVA. Resultados: Se observó una asociación entre el consumo de los alimentos anunciados y la frecuencia en la que se anuncian en la TV. También se observó una asociación entre las horas de televisión, el IMC de las madres y el puntaje Z-score de los niños. Conclusiones: Se observó una asociación entre las horas de televisión y los indicadores de adiposidad en las madres y los niños. El mayor aumento en la exposición a la TV puede incrementar el riesgo de obesidad infantil.
