Objective. To determine the level of stability or change in topic areas published by public health journals in Latin America and the Caribbean, using Keywords: and co-word analysis, in order to support evidence-based research planning. Methods. Keywords: were extracted from papers indexed in Scopus® that were published by the Revista de Salud Pública (RSP; Colombia), the Salud Pública de México (SPM; Mexico), and the Revista Peruana de Medicina Experimental y Salud Pública (RPMESP; Peru) for three periods: 2005 - 2007, 2008 - 2010, and 2011 - 2013. Co-word analysis was used to examine keywords extracted. Textual information was analyzed using centrality measures (inbetweenness and closeness). The hypothesis of stability/change of thematic coverage was tested using the Spearman's rho correlation coefficient. VOSviewer was used to visualize the co-word maps. Results. A moderate level of change in thematic coverage was observed in 2005 - 2010, as evidenced by the correlation coefficients for two of the 3-year periods, 2005 - 2007 and 2008 - 2010: 0.545 for RSP and 0.593 for SPM. However, in 2008 - 2013, more keywords remained constant from one period to the next, given the size of the correlation coefficients for the last 3-year periods: 2008 -- 2010 and 2011 - 2013: 0.727 for RSP and 0.605 for SPM. Conclusion. The research hypothesis was partially accepted given that just two consecutive 3-year periods showed a statistically-significant degree of stability in thematic coverage in public health studies. In that sense, this study provides compelling evidence of the effectiveness of using a combined approach for examining the dynamics of thematic coverage: centrality measures for identifying the main keywords and visual inspection for detecting the structure of textual information.

This paper discusses the gestation process, implementation methodology, and results obtained from the initiative to use e-learning to train human resources for health, six years after the launch of the Virtual Campus of Public Health of the University of Guadalajara (Mexico); the discussion is framed by Pan American Health Organization (PAHO) standards and practices. This is a special report on the work done by the institutional committee of the Virtual Campus in western Mexico to create an Internet portal that follows the guidelines of the strategic model established by Nodo México and PAHO for the Region of the Americas. This Virtual Campus began its activities in 2007, on the basis of the use of free software and institutional collaboration. Since the initial year of implementation of the node, over 500 health professionals have been trained using virtual courses, the node’s educational platform, and a repository of virtual learning resources that are interoperable with other repositories in Mexico and the Region of the Americas. The University of Guadalajara Virtual Campus committee has followed the proposed model as much as possible, thereby achieving most of the goals set in the initial work plan, despite a number of administrative challenges and the difficulty of motivating committee members.

In Ciudad Juarez, Chihuahua, Mexico, morbidity and mortality from injuries have increased alarmingly since 2008. This paper aims to examine the changes in the number of hospital discharges for external injuries recorded during the 2008-2010 period in a hospital in Ciudad Juarez. A descriptive retrospective study conducted at the Ciudad Juarez General Hospital looked at the incidence of external injuries as the reason for hospital discharges during the period under analysis. The average proportion of hospital discharges attributed to external injuries was 27%, with the 25-44-year-old age group being the most affected. More than half of the discharges were for fractures. The incidence rate of hospital discharges attributed to injuries in Ciudad Juarez was almost four times greater than that reported at the national level. [ABSTRACT FROM AUTHOR]

This paper reviews and discusses the main procedures and policies that need to be followed when designing and implementing a binational survey such as the United States of America (U.S.)-Mexico Border Diabetes Prevalence Study that took place between 2001 and 2002. The main objective of the survey was to determine the prevalence of diabetes in the population 18 years of age or older along U.S.-Mexico border counties and municipalities. Several political, administrative, financial, legal, and cultural issues were identified as critical factors that need to be considered when developing and implementing similar binational projects. The lack of understanding of public health practices, implementation of existing policies, legislation, and management procedures in Mexico and the United States may delay or cancel binational research, affecting the working relation of both countries. Many challenges were identified: multiagency/multifunding, ethical/budget clearances, project management, administrative procedures, laboratory procedures, cultural issues, and project communications. Binational projects are complex; they require coordination between agencies and institutions at federal, state, and local levels and between countries and need a political, administrative, bureaucratic, cultural, and language balance. Binational agencies and staff should coordinate these projects for successful implementation. [ABSTRACT FROM AUTHOR]

Objectives. To determine the prevalence of Trypanasoma cruzi antibodies among the population under 18 years of age in the state of Veracruz, Mexico, and to identify risk factors associated with housing conditions and vector presence and distribution. Methods. A cross-sectional, epidemiological study of the population under 18 years of age living in 10 of the 11 health districts of the state of Veracruz, Mexico, from 2000 to 2001. Presence of T. cruzi antibodies was determined by hemagglutination inhibition test (HAl) and enzyme-linked immunosorbent assays (ELISA) of serum samples spotted on filter paper, and confirmed by HAl, ELISA, and indirect immunofluorescence assay (IFA) on serum samples. A questionnaire was administered to determined housing conditions, and entomological indices for triatomines were calculated for both the intra- and peridomiciliary areas. The results were analyzed using bifactorial and multifactorial unconditional logistic regression. Results. Of the 150 individuals presenting an initial reaction, 14 were confirmed positive (5 by HAl, ELISA and IFA; 6 by HAl and ELISA, and 3 by ELISA and IFA), for a total prevalence rate of 0.91% (95% CI: 0.85–0.94). All of the confirmed-positive cases were from five of 14 health districts, with the Tuxpan district having the highest prevalence rate: 5.2% (95%CI: 1.2–9.0). Risk factors included having noticed cracks in the house walls and gaps in the roof. The only species of vector captured was Triotoma dimidiata. The entomologic indices for infestation, colonization, and natural infection were: 10.9%, 50.0%, and 9.0%, respectively. Conclusions. Active, vector-borne transmission of T. cruzi was confirmed in the state of Veracruz, Mexico, with an overall antibody seroprevalence rate of 0.19% among the population under 18 years of age. Seroprevalence rates among this segment of the population, which serves as a sentinel group, should be closely monitored to determine if more stringent methods of vector control and epidemiological surveillance are needed.
