Polycyclic aromatic hydrocarbons (PAHS) (I): Toxicity, population exposure and involved foods

Food is one of the main exogenous sources of genotoxic compounds. In heated food products, polycyclic aromatic hydrocarbons (PAHs) represent a priority group of genotoxic, mutagenic and/or carcinogenic chemical pollutants with adverse long-term health effects. People can be exposed to these compounds through different environments and via various routes: inhalation, ingestion of foods and water and even percutaneously. The presence of these compounds in food may be due to environmental contamination, to industrial handling and processing of foods and to oil processing and refining. The highest levels of these compounds are found in smoked foods, in seafood which is found in polluted waters, in grilled meats and, to a lesser extent, in vegetable fats and oils. Lower levels of PAHs are found in vegetables and in cereals and its products.

The University Programmes for Senior Citizens and their contribution of lifelong learning

The study addresses the essential features of University Programmes for senior citizens (PUM). It committed to the lifelong education through the integration of the elderly in the University. Part of the base that is learned during the entire life cycle, there is no age, no specific space for education. Learning is constructed from knowledge, abilities, skills and aptitudes that are enriched continuously. It is necessary to ensure the elderly to age in a healthy way. It calls for active ageing, effective tool against isolation and social exclusion. The aim is to discover aspects of the UNED Senior training programme that contribute to lifelong learning and satisfaction produced. The PUM are ways for the promotion of aging along with other activities aimed to enhance a creative leisure, access to culture, facilitate training on topics of interest and create a means of participation in all spheres of society. In this research has resorted to a mixed methodology. Their wealth combines the methods of quantitative and qualitative allowing us to obtain information and contrast from different perspectives. The purpose is to verify the results of the investigation. The sample consists of 639 students, 57 teachers and 15 coordinators. The results indicate that the PUM of the UNED Senior is highly satisfactory for those involved, by the adequacy between interests and expectations. Fruit of this research are the conclusions and suggestions for improvement.

Proprioception in ankle sprain from exercises and bandages

Ankle sprains are the most common injuries in sports, usually causing damage to the lateral ligaments. Recurrence has as usual result permanent instability, and thus loss of proprioception. This fact, together with residual symptoms, is what is known as chronic ankle instability, CAI, or FAI, if it is functional. This problem tries to be solved by improving musculoskeletal stability and proprioception by the application of bandages and performing exercises. The aim of this study has been to review articles (meta-analisis, systematic reviews and revisions) published in 2009-2015 in PubMed, Medline, ENFISPO and BUCea, using keywords such as “sprain instability”, “sprain proprioception”, “chronic ankle instability”. Evidence affirms that there does exist decreased proprioception in patients who suffer from CAI. Rehabilitation exercise regimen is indicated as a treatment because it generates a subjective improvement reported by the patient, and the application of bandages works like a sprain prevention method limiting the range of motion, reducing joint instability and increasing confidence during exercise. As podiatrists we should recommend proprioception exercises to all athletes in a preventive way, and those with CAI or FAI, as a rehabilitation programme, together with the application of bandages. However, further studies should be generated focusing on ways of improving proprioception, and on the exercise patterns that provide the maximum benefit.
