Resultados: De 795 artículos publicados hasta febrero 2016 identificados en las bases de datos electrónicas y literatura gris, se seleccionaron por consenso nueve estudios. Los estudios mostraron una reducción significativa del TNSS de -2,61 (-3.32 a -1,90) de la terapia combinada de Montelukast más antihistamínicos orales en comparación con la monoterapia de cada uno de ellos. Los estudios reportaron que la seguridad de la terapia combinada de Montelukast más antihistamínicos orales no fue diferente a la monoterapia. Conclusiones: La terapia combinada de Montelukast con antihistamínico redujo el puntaje de TNSS en -2,61 (-3.32 a -1,90) por lo que es eficaz y seguro en pacientes con rinitis alérgica.

The institutional environment and its influence on political options to Protect Winnipeg’s Female garments Workers against the impact of globalization

The principal objective of this paper is to identify the relationship between the re­sults of the Canadian policies implemented to protect female workers against the impact of globalization on the garment industry and the institutional setting in which this labour market is immersed in Winnipeg. This research paper begins with a brief summary of the institutional theory appro­ach that sheds light on the analysis of the effects of institutions on the policy options to protect female workers of the Winnipeg garment industry. Next, this paper identi­fies the set of beliefs, formal procedures, routines, norms and conventions that cha­racterize the institutional environment of the female workers of Winnipeg’s garment industry. Subsequently, this paper descri­bes the impact of free trade policies on the garment industry of Winnipeg. Afterward, this paper presents an analysis of the ba­rriers that the institutional features of the garment sector in Winnipeg can set to the successful achievement of policy options addressed to protect the female workforce of this sector. Three policy options are considered: ethical purchasing; training/retraining programs and social engage­ment support for garment workers; and protection of migrated workers through promoting and facilitating bonds between Canada’s trade unions and trade unions of the labour sending countries. Finally, this paper concludes that the formation of isolated cultural groups inside of factories; the belief that there is gender and race discrimination on the part of the garment industry management against workers; the powerless social conditions of immi­grant women; the economic rationality of garment factories’ managers; and the lack of political will on the part of Canada and the labour sending countries to set effective bilateral agreements to protect migrate wor­kers, are the principal barriers that divide the actors involved in the garment industry in Winnipeg. This division among the prin­cipal actors of Winnipeg’s garment industry impedes the change toward more efficient institutions and, hence, the successful achievement of policy options addressed to protect women workers. 

The impact of a minimum pension on old age poverty and its budgetary cost. Evidence from Latin America

This paper examines the impact on old age poverty and the fiscal cost of universal minimum oldage pensions in Latin America using recent household survey data for 18 countries. Alleviatingold age poverty requires different approach from other age groups and a minimum pension islikely to be the only alternative available. First we measure old age poverty rates for all countries.Second we discuss the design of minimum pensions schemes, means-tested or not, as wellas the disincentive effects that they are expected to have on the economic and social behavior ofhouseholds including labor supply, saving and family solidarity. Third we use the household surveysto simulate the fiscal cost and the impact on poverty rates of alternative minimum pensionschemes in the 18 countries. We show that a universal minimum pension would substantiallyreduce poverty among the elderly except in Argentina, Brazil, Chile and Uruguay where minimumpension systems already exist and poverty rates are low. Such schemes have much tobe commended in terms of incentives, spillover effects and administrative simplicity but have ahigh fiscal cost. The latter is a function of the age at which benefits are awarded, the prevailinglongevity, the generosity of benefits, the efficacy of means testing, and naturally the fiscal capacityof the country.

Teleconsultation in sexual and reproductive health for young adults through mobile devices: Experience in Colombia

Background: Sexual risk behaviors associated with poor information on sexuality have contributed to major public health problems in the area of sexual and reproductive health in teenagers and young adults in Colombia. Objective: To measure the perception of changes in sexual and reproductive risk behavior after the use of a teleconsultation service via mobile devices in a sample of young adults. Methods: A before and after observational study was designed, where a mobile application to inquire about sexual and reproductive health was developed. The perception of changes in sexual and reproductive health risk behaviors in a sample of young adults after the use of the application was measured using the validated survey “Family Health International (FHI) – Behavioral Surveillance Survey (BSS) – Survey for Adults between 15 to 40 Years”. Non-probabilistic convenience recruitment was undertaken through the study´s web page. Participants answered the survey online before and after the use of the mobile application for a six month period (intervention). For the inferential analysis, data was divided into three groups (dichotomous data, discrete quantitative data, and ordinal data), to compare the results of the questions between the first and the second survey. For all tests, a confidence interval of 95% was established. For dichotomous data, the Chi-squared test was used. For quantitative data, we used the Student’s t-test, and for ordinal data, the Mann-Whitney-Wilcoxon test. Results: A total of 257 subjects were registered in the study and met the selection criteria. The pre-intervention survey was answered by 232 subjects, and 127 completely answered the post-intervention survey, of which 54.3% did not use the application, leaving an effective population of 58 subjects for analysis. 53% (n=31) were female, and 47% (n=27) were male. The mean age was 21 years, ranging between 18 and 40 years. The differences between the answers on the first and the second survey were not statistically significant. The main risk behaviors identified in the population were homosexual relations, non-use of condoms, sexual relations with non-regular and commercial partners, the use of psychoactive substances, and ignorance about the symptoms of sexually transmitted diseases and HIV transmission. Conclusions: Although there were no differences between the pre- and post-intervention results, the study revealed different risk behaviors among the participating subjects. These findings highlight the importance of promoting educational strategies on this matter and the importance of providing patients with easily accessible tools with reliable health information.
