Objetive: Cardiovascular diseases that every year have more prevalence in the country, are the product of risky factors, many of them modifiable and preventable. The objective of the present study has been to know and analyze the factors of cardiovascular risk and determine the vascular age in the population of Lima. Material and methods: A descriptive cross sectional study, carried out in March 2016, in the southern, northern and eastern cones of Metropolitan Lima, in people older than 30 and younger than 75 years old. The survey structured for the study collected the following variables: gender, age, arterial hypertension, smoking, diabetes, physical activity and type of diet. Blood presure, weight and tall were recorded. Results: In total, 485 participants were included, 197 men and 288 women. The age was 49,5± 9,9 years old. The more frequent risky factor was the unhealthy diet (47,...

Intelligent packaging represents a sustainable solution for food preservation by enabling the monitoring of freshness through chromatic changes. In this study, a biofilm based on polyvinyl alcohol (PVA), nanocellulose (NC) extracted from rice straw and blueberry extract was developed and evaluated for its performance as a visual freshness indicator in tilapia fillets. Nanocellulose, obtained by TEMPO oxidation, exhibited proper integration into the polymeric matrix according to transmission electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis and X-ray diffraction analysis. The biofilms improved their mechanical properties with the addition of NC, by increasing tensile strength and reducing water solubility. However, the incorporation of anthocyanins increased solubility and water vapor permeability due to their hydrophilic character. Despite this, the...
