RESUMO
In the Chilean indigenous culture, the tree Drimys winteri (Winteraceae) Canelo is of great importance and is considered the sacred Mapuche tree. It has antibacterial and disinfectant properties and is used in the treatment of various diseases, such as fevers, ulcers, cancers, and respiratory tract problems. The essential oil obtained from D. winteri, DW_EO, is bioactive, possesses insecticidal and repellent properties against pests, and shows activity toward plant growth regulators. It also has a phytotoxic effect against the growth and germination of weeds. The essential oil obtained from the leaves and bark of Drimys winteri has demonstrated antifungal, immunomodulatory, anti-inflammatory, and anticancer properties in in vitro and in vivo studies. It also possesses antioxidant activity and antibacterial effects. The essential oil contains monoterpenes such as zafrol, pinenes, and linalool, among others, that contribute to its bioactivity. The DW_EO and bioactive compounds have great potential in various applications in medicine, industrial food, sanitizer, and other areas.
RESUMO
Introducción: el cáncer es una de las primeras causas de muerte mundial; en 2012 representó 8.2 millones de muertes. En México, a pesar de que la incidencia de cáncer de próstata es tres veces menor que lo observado en Estados Unidos, la mortalidad por esta causa es prácticamente igual (11.3 vs 9.8 muertes por cada 100,000 hombres) y representa la primera causa de cáncer y mortalidad por cáncer en hombres, por lo que es de vital importancia la prevención y para ello se debe promover el conocimiento de esta afección. Objetivo: identificar el nivel de conocimientos sobre la prevención del cáncer de próstata en hombres de 40 a 65 años de la Unidad de Medicina Familiar No. 51. Metodología: estudio descriptivo transversal. Se aplicó un cuestionario validado (alfa de Cronbach de 0.8) sobre las medidas preventivas del cáncer prostático a 204 derechohabientes masculinos de la unidad. Resultados: el grado de conocimientos sobre la prevención del cáncer de próstata es bajo en el 66% de los casos, me- dio en el 31% y alto en el 3%; el 78.9% de los participantes corresponde a casados, el 51.5% tiene grado de estudios de preparatoria o superior y el 47.1% es obrero. Conclusiones: el bajo grado de conocimientos en la prevención del cáncer prostático muestra un área de oportunidad de mejorar si se difunde a edades tempranas.
Introduction: Cancer is one of the leading causes of death worldwide; in 2012, 8.2 million deaths were attributed to it. In Mexico, despite the fact that the incidence of prostate cancer is three times lower than that observed in the United States, mortality from this cause is practically the same (11.3 vs. 9.8 deaths per 100 000 men) and represents the first cause of cancer and cancer mortality in men, which is why prevention is of vital importance, and for this, knowledge about the pathology must be promoted. Objective: To identify the level of knowledge about the pre- vention of prostate cancer in men between 40 and 65 years from the Family Medicine Unit No. 51. Methodology: Descriptive cross-sectional study. A validated questionnaire (Cronbach's alpha of 0.8) on preventive measures of prostate cancer was applied to 204 male beneficiaries from the aforementioned unit. Results: The level of knowledge about the prevention of prostate cancer is low in 66% of the cases, medium in 31% and high in 3%; 78.9% are married, 51.5% have a high school education level or higher and 47.1% are workers. Conclusions: The low level of knowledge of prostate cancer prevention shows an area of opportunity for improvement with a greater emphasis on early ages.
