Del 28 al 30 de juny de 1989 se celebra a Girona el I Curs d'Estiu de Geografia, en el marc dels Cursos d'Estiu de l'Estudi General de Girona -Universidad Internacional Menéndez y Pelayo. La primera edició d'aquest curs es dedica a la geografia regional. Es tractava d'impulsar una discussió a fons sobre la revifalla del concepte de regió, observada no solament des d’algunes de les perspectives geogràfiques més innovadores, sinó també des d'altres camps de les ciències socials i humanes. Ens trobem davant d'una seriosa reconsideració teòrica i metodològica de la perspectiva regional, que inclou, alhora, una suggeridora reflexió sobre el paper que el lloc, el context espacial, té o hauria de tenir en l'explicació dels fenòmens socials, polítics i econòmics que afecten la nostra vida quotidiana. El text que segueix a continuació és una breu noticia de l’esmentat curs

BACKGROUND. Maternal genetics and feeding before and during pregnancy, different maternal metabolic pathologies, as well as nutrient intakes of newborns in their first months of life may be involved in the obesity aetiology and its long-term consequences. The possible role of these and others factors, the mechanisms and the effects on the metabolism, and the development of this disease need further research. OBJECTIVE. To acquire more knowledge about foetal adipose tissue development and the influence of genetic, dietetic and environmental factors on the risk to suffer from obesity. METHODOLOGY. Four study groups have been established with 30 pregnant women in each one: 1) control group; 2) mothers with glucose intolerance/gestational diabetes; 3) women with low weight gain during pregnancy, and 4) women with overweight/obesity at the beginning of the pregnancy. The magnitudes to be studied are: 1) dietary intake; 2) life-style habits; 3) physical activity; 4) anthropometry and body composition; 5) haematological study; 6) biochemical study (lipid and metabolic biomarkers); 7) immune function profile related to nutritional status; 8) psychological profile; 9) genetic biomarkers, and 10) microbiological markers; all of them in relation to the development of the foetal adipose tissue in the first stages of life and the risk of suffering from obesity in the future. CONCLUSION. This project, coordinated by the Department of Paediatrics of the School of Medicine in the University of Granada, and with the collaboration of well-known and expert research groups, tries to contribute to the knowledge about the obesity aetiology in infancy and its subsequent development in later periods of life.

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.

Chronic renal failure is commonly related to hyponutrition, affecting approximately on third of patients with advanced renal failure. We carried out a longitudinal study to assess nutritional evolution of 73 patients on a regular hemodialysis program, assessing changes in the anthropometrical parameter body mass index (BMI) and its correspondence to biochemical nutritional parameters such as total protein (TP) levels and serum albumin (Alb). Every three months plasma TP and albumin levels were collected and BMI was calculated by the standard formula: post-dialysis weight in kg/height in m2. For classifying by BMI categories, overweight and low weight were defined according to the WHO Expert Committee. Studied patients had a mean age of 53 years, 43 were male and 30 were female patients. BMI in women was lower than that in men (p < 0.001), as well as TP (p < 0.001) and Alb (p < 0.001) levels. Mean BMI was 29.3 kg/m2. Three point two percent of the determinations showed low weight, 12.16% overweight, and 83.97% normal BMI. TP were normal in 90.76% and decreased in 9.24%. Alb was normal in 82.2% and low in 17.78%. After the follow-up time (21.6 months, minimum 18 months, maximum 53 months), the Kruskal-Wallis test did not show a statistically significant change for BMI but it did show a change for the biochemical parameters albumin and total proteins (p < 0.05): nutritional impairment in CRF patients is manifested on biochemical parameters (TP and Alb) with no reflection on anthropometrical data.

El lluç europeu del Golf de Lleó és una espècie amb un gran valor comercial a les llotges catalanes per la qual cosa es troba sobreexplotat. Els paràmetres indicadors de la condició física avaluen la salut dels peixos i poden ajudar a predir la productivitat de les poblacions explotades. Un factor que pot estar relacionat amb la condició és el parasitisme, tot i que les investigacions en aquest sentit són molt escasses. Aquest estudi avalua per primera vegada la relació entre parasitisme i condició del lluç europeu. S’han examinat 30 individus, entre gener i març de 2010, i s’han localitzat paràsits que s’han classificat com a nematodes, cestodes, copèpodes i trematodes. S’han calculat també, els índexs de condició Le Cren, índex hepatosomàtic, índex gonodosomàtic i contingut lipídic en fetge i gònades. Els resultats d’aquest estudi suggereixen que els lluços infectats amb copèpodes tenen una quantitat inferior de lípids al fetge, la qual cosa podria indicar una menor condició física. Malgrat tot, cal disposar de més mostres per poder afirmar aquest fet, així com una sèrie temporal de dades que comprengui totes les estacions de l’ any

The aim of this study was to analyze the sagittal spinal morphology of thoracic and lumbar spine in standing and sitting in women workers from a cooperative in the production, handling and marketing business of vegetable and fruit products. A total of 50 women (mean age: 43.62±8.43 years old) were evaluated. The Spinal Mouse system was used to mesasure the sagittal thoracic and lumbar curvatures in standing and relaxed sitting. The values for thoracic and lumbar curvatures were 32.74±8.76 and -21.66±19.12 in standing and 36.32±10.55 and -1.08±18.14 in sitting. A high frequency (86.0% and 68.3%) of normal thoracic kyphosis and lumbar lordosis were found in standing posture. While sitting the 74.0% and 20.0% presented thoracic hyperkyphosis and lumbar kyphosis. In conclusion, a high percentaje of women workers presented normality values in standing posture, although a high percentage of women were found with thoracic hyperkyphosis and lumbar flexed while sitting relaxed. It is recommended that these women carry out a program to improve their actitudinal postures in their work place.

Se desarrollaron catalizadores de TiO2 dopados con nitrógeno para conseguir actividad fotocatalítica bajo irradiación visible. En este trabajo se reporta la síntesis de TiO2-N, usando urea y nitrato de amonio (NH4NO3) como precursores de nitrógeno, tanto a partir de un TiO2 generado in situ (método sol-gel) como mediante la modificación de un TiO2 comercial. Así mismo, se varió la concentración de urea para encontrar el valor óptimo de nitrógeno, lo cual se comprobó mediante la oxidación fotocatalítica de ácido oxálico bajo irradiación con luz visible. Los materiales sintetizados se caracterizaron por medio de análisis elemental, y por reflectancia difusa UV-visible, encontrándose nitrógeno en todas las muestras, y un valor del ancho de banda prohibida en el rango 2-2,8 eV. Lamentablemente, se detectó una pérdida de nitrógeno cuando los fotocatalizadores eran reutilizados, lo cual causó una disminución de su actividad después de cada reacción, ya sea en presencia de oxígeno, o en ausencia de éste mientras se generaba hidrógeno. Entre los dopantes investigados el NH4NO3 mostro una mejor eficiencia en la producción de hidrógeno. Además, los resultados experimentales revelaron claramente que la deposición de platino en la superficie de los catalizadores TiO2-N desempeña un papel fundamental en el aumento de la generación de hidrógeno. Sin embargo, esta mejora dependía claramente del método de preparación de las muestras, obteniéndose mejores resultados con el TiO2-p25.

The aim of this research is to know the barriers and opportunities that nursing professionals detect in their clinical practice in order to develop the culture of patient safety and to identify future research lines. This qualitative study is based on the DELPHI method, with a group of 19 nursing professionals from education and care practice, involving both primary and specialized care. Weaknesses and threats revolve around five categories: profession, organization and infrastructure; indicators; communication and safety culture; and safety training. Opportunities to improve safety cover six categories: organizational change; promotion of the safety culture, professional training and development; relationship with the patients; research; and strategic planning. Work is needed to improve safety and nursing should be ready to assume this leadership.
