Efectos del consumo de aceites termo-oxidados sobre la peroxidación lipídica en animales de laboratorio.

INTRODUCTION The quality of fats and oils used for frying is as important as the quality of the final product since during the frying process oxidization by-products are formed and become part of the diet, being potentially harmful for the consumers' health. OBJECTIVE To determine the effects of thermo-oxidised fats and oils on the oxidization of plasma lipoproteins inexperimental rats. METHODS Determination by means of spectrophotometric techniques of those substances reacting with thiobarbituric acid and total cholesterol (enzymatic method) in the sera of 40 Wistar rats that consumed crude thermooxidised oils and fats with different levels of malonil aldehyde(MDA) for 30 days. RESULTS The group of rats receiving a diet with thermooxidised oils and fats experienced significant increases in MDA plasma levels throughout the study period, lipid peroxidation being higher with increasing MDA content (p < 0.05) regardless the type of fat compound consumed. However, those rats receiving crude oils and fats kept plasma levels of lipidic peroxides without significant changes throughout the experimental period (p > 0.05). By contrast, cholesterol levels increased towards the end of the experimental period in both the rats consuming crude fats and those consuming thermo-oxidised fats (p < 0.05). CONCLUSIONS Consumption of oils and fats submitted to repeat thermal heating has an influence on plasma lipidic peroxidation, which becomes higher with increasing number of heating processes applied, so that it would advisable not to abuse of reheating the oils used for frying foods.

Estudio bibliométrico de la revista Nutrición Hospitalaria en el periodo 2001 a 2005: parte 2, análisis de consumo; las referencias bibliográficas.

OBJECTIVE To describe and assess the consumption of the information consulted and cited in the articles published in the journal Nutrición Hospitalaria for the period 2001--2005 by means of bibliometric analysis. METHOD Cross-sectional descriptive analysis of the results obtained from the analysis of the lists of bibliographic references of the articles published at Nutrición Hospitalaria. We studied the most cited journals, the signatures index, the type of document referred, the publication language, the distribution of geographical origin, and obsolescence and readiness index. We took into account all types of documents with the exception of Communications to Congresses. RESULTS 345 articles were published at Nutr Hosp, containing 8,113 bibliographic references, with a median of 18, a maximum of 136 and minimum of 0 BR per article. The mean (rate of publications per published article during the specified period) is 23.52 (95% IC 20.93-26.10) and the mean at 5% is 20.66 per article. The 25th and 75th percentiles are 6 and 32, respectively, the interquartile interval being 26 BR per document. The semi-period of Burton and Kebler is 7 years and the Price Index is 38.18%. CONCLUSION The bibliographic references, the consumption of information, of the articles published at Nutrición Hospitalaria present parameters similar to other journals on health science. However, good data on obsolescence are observed, which reveal the good validity of most of the references studied.

Perspectivas de salud ambiental en la investigación de brotes epidémicos asociados con una zona de abastecimiento de aguas de consumo humano.

Introduction. The purpose of this work was studied the magnitude, possible causes and contributing environmental factors in the waterbourne outbreaks appearance, in the performance area of the locality of Benaoján (Town of Málaga. Spain). Material/Methods. Analysis of the potability of the water and disinfection controls. Evaluation of the fulfillment of the quality of the drinking water and sanitary technical requirements of water supplies, pursuant to the Spanish regulation on public consumption waters. Results. We have been accomplished 110 potability analysis, proving that 13,4% of the samples do not comply with the potability criteria of the water. It were practiced 647 controls of disinfection, of those which 53% resulted not accordant. The design of the supply net is of the branching type and at least presents 30 blind branches, points where the water remains stagnant. The municipal waters service doesn´t make analytics controls of the quality of the water neither has implanted Standard Operating Procedures (SOPs) of the facilities of the supply. Discussion. Environmental research suggests that the public water supply net is a source of infection, problem related to the epidemic outbreaks appearance. Because of this the water consumption not treaty must be avoided.

Efectos de la deficiencia de yodo sobre variables intelectuales en una población infantil.

An association between severe iodine deficiency and poor mental development has been found in many studies. We examined the relationship between moderate or mild iodine deficiency and intellectual capacity in order to determine whether problems common to severe iodine deficiency (including mental retardation) also emerge in a more subtle form. We also wished to know whether the classic methodology (comparing iodine-deficient zones with nondeficient zones) is the most adequate, and propose to combine this grouping by zones with urinary iodine presented by individuals in each zone. We measured IQ, manipulative and verbal capacity, attention, visual motor ability and disruptive behaviour, variables that have barely been studied in this kind of investigations. The sample comprised 760 schoolchildren from the province of Jaén (southern Spain). Our results show that children with low levels of iodine intake and with urinary iodine concentration lower than 100 microg/litre had a lower IQ and displayed more disruptive behaviour than children with high levels of the criteria. The other variables were not associated with iodine deficiency.
