The use of the medicinal plant Ginkgo biloba has increased worldwide. However, G. biloba is capable of assimilating both essential and toxic metals, and the ingestion of contaminated products can cause damage to health. The aim of this study was to investigate the safety of manganese (Mn), copper (Cu), lead (Pb), arsenic (As), and cadmium (Cd) in 26 items containing Ginkgo biloba (pharmaceutical herbal products, dietary supplements, and traditional herbal remedies) purchased in the metropolitan area of Mexico City. Metal analysis was performed using a graphite furnace atomic absorption spectrometer. All of the products were contaminated with Pb, 54% of them with As, and 81% with Cd. The lowest values of Pb, As, and Cd were detected in pharmaceutical herbal products > dietary supplements > traditional herbal remedies. The daily intake dose (DID) of pharmaceutical herbal products was within the established limits for the five metals. Dietary supplements and traditional herbal remedies exceeded the DID limits for Pb. The hazard quotients estimation and non-carcinogenic cumulative hazard estimation index for Mn, As, and Cd indicated no human health risk. Our results suggest that products containing G. biloba for sale in Mexico are not a health risk.

Resilient Behavior

The objective of this study was to estimate the ratio of resilient youth and compare this to youth with aggressive behavior, and to youth who also exhibit sexually risky behavior and drug use. A cross-section study of a representative sample of people between aged between 12 and 60 who are residents of Medellin, Colombia, and its metropolitan area (N = 4,654) was employed using probabilistic multi-stage sampling. Youth between 14 and 26 years old were selected for the present analysis (n = 1,780). The proportion of resilient youth is 22.9%, of aggressors is 11.3%, and that of youth with other risky conduct is 65.8%. The high ratio of resilient youth calls for a reorientation of public policy toward prevention and control of violence, prioritizing the promotion of resilient behavior instead of continuing with tertiary prevention actions.

Depth Interviews

Nowadays, several mega-trends capture the attention of governments, academia and the public in general given their implications for the quality of life and the development of nations. This work deals with two of them: entrepreneurship and environmental protection, as a result of research aimed at analyzing the processes, actors and results of the “Entrepreneurship for Life” Program led by the Valle de Aburrá Metropolitan Area, executed during the period from 2012 to 2015, in order to contribute to the improvement of public policies on eco-entrepreneurship. The methodology of the Synergy System1, applied by the Colombian Government, was used to appraise public policies. The required information was collected through in-depth interviews with the creator of the program, the entrepreneurs who benefited from it, officials of the entities involved and experts. Then, it was complemented by the analysis of documents such as minutes, reports and other sources. Among other results, it was evident that, although the public policy on environmental entrepreneurship is still incipient, the evaluated Program met the objectives for which it was created.
