Descripció i anàlisi dels factors protectors d’adolescents en la prevenció del delicte: el perfil de l’adolescent desistent i les competències emocionals associades

En els darrers anys, ha augmentat l’interès per l’estudi de la prevenció i la protecció de la delinqüència juvenil. En aquest context els conceptes vinculats són els de desistiment i resiliència. L’objectiu principal d’aquest estudi és aprofundir en el concepte de desistiment i els factors de protecció, primer en el pla teòric i després en l’àmbit empíric. L’estudi consta de dues parts: la primera descriptiu el perfil del menor desistent a la Direcció General de Justícia Juvenil, i la segona mostra enquestes en què s’avaluen les dimensions de la competència emocional en un grup d’adolescents infractors. A partir d’una mostra de 288 adolescents infractors, 86 reincidents i 202 desistents, de les comarques del Baix Llobregat, Garraf, Alt Penedès i d’alguns municipis de l’Anoia, s’analitzen les diferències sociodemogràfiques, criminològiques i de recorregut educatiu fet a la Direcció General de Justícia Juvenil. A continuació, participen de l’estudi per enquesta una mostra accidental de 101 adolescents, 45 reincidents i 56 desistents, procedents dels programes de mediació, medi obert i internament. Els adolescents desistents en el delicte obtenen puntuacions superiors als reincidents, diferències que són estadísticament significatives en la dimensió de competència social i en la puntuació total de competència emocional.

Occurrence of Cryptosporidial Oocysts and Giardia Cysts in Bottled Mineral Water Commercialized in the City of Campinas, State of São Paulo, Brazil

The consumption of bottled mineral water has significantly increased in Brazil so that it is in the interest of public health to determine the parasitological and microbiological status of some brands of Brazilian mineral water available in the town of Campinas, São Paulo, Brazil. For this purpose, detection of protozoa by direct immunofluorescence technique and microbiological parameters were determined for each specimen after membrane filtration. Giardia cysts were not present while cryptosporidial oocysts were detected in two samples. The counts of protozoa varied from 0.2 to 0.5 oocysts/l. The detected level of Pseudomonas aeruginosa and heterotrophic bacteria reflected the level of organic enrichment of the water.

Perfil clínico y curso evolutivo de los pacientes tratados con efalizumab tras la suspensión de su autorización por la EMEA. Estudio observacional y multicéntrico

L’objectiu de l’estudi fou avaluar el curs de la psoriasi després de la suspensió forçosa de l’efalizumab en un grup de 147 pacients procedents de 12 hospitals. Es recollí informació referida al perfil epidemiològic, al curs de la dermatosi durant el tractament i a l’evolució després de la suspensió. Durant el tractament, un 4% dels pacients fou diagnosticat d’exacerbació inflamatòria. Bona part dels pacients van ser classificats com a bons responedors, grup a priori de millor pronòstic. Tot i així, després de la suspensió, un 30% van desenvolupar rebot. La probabilitat de rebot fou independent de qualsevol dels paràmetres avaluats.

El perfil formativo del gestor cultural en España

En la actualidad la base de conocimientos de todo gestor cultural, al igual que el resto de ofertas de grado y postgrado en las universidades de los países acogidas al Espacio Europeo de Educación Superior (EEES) se encuentra en profunda transformación: conceptos como la formación a lo largo de la vida, los distintos ciclos universitarios y el sistema de competencias se presentan a una oferta formativa ya de por sí, históricamente heterogénea. Dada tanta diversidad, nuestro proyecto se va a centrar en: evolución del concepto de cultura en España en los últimos 30 años, contextualizar históricamente la evolución de la profesión de gestor cultural en España, analizar los agentes culturales principales que actúan en nuestro país, examinar los principales cambios que supone el proceso de Bolonia en las universidades españolas (itinerarios curriculares, competencias, etc.)

Have all the men and women with a fragility fracture a low bone mineral density? A Nationwide Swiss Survey : FM3

Background: The prevalence of a low bone mineral density (T-score <-1 SD) in postmenopausal women with a fragility fracture may vary from 70% to less than 50%. In one study (Siris ES. Arch Intern Med. 2004;164:1108-12), the prevalence of osteoporosis was very low at 6.4%. The corresponding values in men are rarely reported. Methods: In a nationwide Swiss survey, all consecutive patients aged 50+ presenting with one or more fractures to the emergency ward, were recruited by 8 participating hospitals (University Hospitals: Basel, Bern, and Lausanne; cantonal hospitals: Fribourg, Luzern, and St Gallen; regional hospitals: Estavayer and Riaz) between 2004 and 2006. Diagnostic workup was collected for descriptive analysis. Results: 3667 consecutive patients with a fragility fracture, 2797 women (73.8 ± 11.6 years) and 870 men (70.0 ± 12.1 years), were included. DXA measurement was performed in 1152 (44%) patients. The mean of the lowest T-score values was -2.34 SD in women and -2.16 SD in men. In the 908 women, the prevalence of osteoporosis and osteopenia according to the fracture type was: sacrum (100%, 0%), rib (100%, 0%), thoracic vertebral (78%, 22%), femur trochanter (67%, 26%), pelvis (66%, 32%), lumbar vertebral (63%, 28%), femoral neck (53%, 34%), femur shaft (50%, 50%), proximal humerus (50%, 34%), distal forearm (41%, 45%), tibia proximal (41%, 31%), malleolar lateral (28%, 46%), malleolar median (13%, 47%). The corresponding percentages in the 244 men were: distal forearm (70%, 19%), rib (63%, 11%), pelvis (60%, 20%), malleolar median (60%, 32%), femur trochanter (48%, 31%), thoracic vertebral (47%, 53%), lumbar vertebral (43%, 36%), proximal humerus (40%, 43%), femoral neck (28%, 55%), tibia proximal (26%, 36%), malleolar lateral (18%, 56%). Conclusion: The probability of underlying osteoporosis or osteopenia in men and women aged 50+ who experienced a fragility fracture was beyond 75% in fractures of the sacrum, pelvis, spine, femur, proximal humerus and distal forearm. The medial and lateral malleolar fractures had the lowest predictive value in women, not in men.

Un análisis de segmentación y perfil de los segmentos de los usuarios de vuelos de bajo coste

El conocimiento sobre los perfiles de los viajeros de bajo coste y de sus preferencias por las diversas características o atributos del vuelo es más bien escaso. La segmentación de mercados es un instrumento útil para los encargados de la toma de decisiones relacionadas con el turismo, ya sean públicos o privados. Esto es particularmente relevante en este contexto, desde el momento que el viaje de bajo coste es una nueva forma de atraer turistas a un destino turístico y no se sabe demasiado sobre las diferentes preferencias y valoraciones de estos viajeros. Este artículo evalúa la diversidad e importancia de estas preferencias mediante la identificación de diferentes segmentos de mercado aplicando un análisis de segmentación a posteriori. La segmentación se ha realizado aplicando técnicas de análisis cluster o de conglomerados sobre los datos obtenidos de una encuesta. A partir de la literatura consultada, se ha planteado como hipótesis que si bien la tarifa (bajo coste o precio bajo) es una variable de primer orden en la formación de posibles segmentos, no es la única, de forma que existen otras relativas a las características del vuelo o de la calidad percibida del destino turístico que también influyen diferenciando preferencias y generando otros potenciales segmentos de usuarios

Bone Mineral Density and Serum Levels of Soluble Tumor Necrosis Factors, Estradiol, and Osteoprotegerin in Postmenopausal Women with Cirrhosis after Viral Hepatitis

CONTEXT: Cirrhosis after viral hepatitis has been identified as a risk factor for osteoporosis in men. However, in postmenopausal women, most studies have evaluated the effect of primary biliary cirrhosis, but little is known about the effect of viral cirrhosis on bone mass [bone mineral density (BMD)] and bone metabolism. OBJECTIVE: Our objective was to assess the effect of viral cirrhosis on BMD and bone metabolism in postmenopausal women. DESIGN: We conducted a cross-sectional descriptive study. SETTING AND PATIENTS: We studied 84 postmenopausal female outpatients with viral cirrhosis and 96 healthy postmenopausal women from the general community. BMD was measured by dual-energy x-ray absorptiometry at lumbar spine (LS) and femoral neck (FN). RESULTS: The percentage with osteoporosis did not significantly differ between patients (LS, 43.1%; FN, 32.2%) and controls (LS, 41.2%; FN, 29.4%), and there was no difference in BMD (z-score) between groups. Serum concentrations of soluble TNF receptors, estradiol, and osteoprotegerin (OPG) were significantly higher in patients vs. controls (P < 0.001, P < 0.05, and P < 0.05, respectively). No significant difference was observed in urinary deoxypyridinoline. Serum OPG levels were positively correlated with soluble TNF receptors (r = 0.35; P < 0.02) and deoxypyridinoline (r = 0.37; P < 0.05). CONCLUSIONS: This study shows that bone mass and bone resorption rates do not differ between postmenopausal women with viral cirrhosis and healthy postmenopausal controls and suggests that viral cirrhosis does not appear to increase the risk of osteoporosis in these women. High serum estradiol and OPG concentrations may contribute to preventing the bone loss associated with viral cirrhosis in postmenopausal women.

Effect of a general school-based physical activity intervention on bone mineral content and density: A cluster-randomized controlled trial.

Background: Specific physical loading leads to enhanced bone development during childhood. A general physical activity program mimicking a real-life situation was successful at increasing general physical health in children. Yet, it is not clear whether it can equally increase bone mineral mass. We performed a cluster-randomized controlled trial in children of both gender and different pubertal stages to determine whether a school-based physical activity (PA) program during one school-year influences bone mineral content (BMC) and density (BMD), irrespective of gender.Methods: Twenty-eight 1st and 5th grade (6-7 and 11-12 year-old) classes were cluster randomized to an intervention (INT, 16 classes, n = 297) and control (CON; 12 classes, n = 205) group. The intervention consisted of a multi-component PA intervention including daily physical education with at least 10 min of jumping or strength training exercises of various intensities. Measurements included anthropometry, and BMC and BMD of total body, femoral neck, total hip and lumbar spine using dual-energy X-ray absorptiometry (DXA). PA was assessed by accelerometers and Tanner stages by questionnaires. Analyses were performed by a regression model adjusted for gender, baseline height and weight, baseline PA, post-intervention pubertal stage, baseline BMC, and cluster.Results: 275 (72%) of 380 children who initially agreed to have DXA measurements had also post-intervention DXA and PA data. Mean age of prepubertal and pubertal children at baseline was 8.7 +/- 2.1 and 11.1 +/- 0.6 years, respectively. Compared to CON, children in INT showed statistically significant increases in BMC of total body, femoral neck, and lumbar spine by 5.5%, 5.4% and 4.7% (all p < 0.05), respectively, and BMD of total body and lumbar spine by 8.4% and 7.3% (both p < 0.01), respectively. There was no gender*group, but a pubertal stage*group interaction consistently favoring prepubertal children.Conclusion: A general school-based PA intervention can increase bone health in elementary school children of both genders, particularly before puberty.

Bottled natural mineral water in catalonia: origin and geographical evolution of its consumption and production

During the second half of the nineteenth century a major mineral water bottling industry appeared in Catalonia which vigorously lasted until the first third of the 20th century. The fact that the industry appeared in Catalonia and in other parts of Europe and the United States almost at the same time and had not existed before can be explained by a series of factors which coincided in time. This situation encouraged producers to pack, transport and sell bottled water from their respective sources. Among these factors there is the rise of hygienism, very influential in Catalonia, the declining water quality due to industrialization, the increase in population density, the improvement in transport, the emergence of thermal tourism or the invention of better containers used to store water. This project aims to explain thoroughly all the mentioned factors, and to give some light to why, when and how the Catalan bottled water industry appeared.

Descripción y análisis de los factores protectores de los adolescentes en la prevención del delito: el perfil del adolescente desistente y las competencias emocionales asociadas

El objetivo principal de este estudio es profundizar en el concepto de desistimiento y los factores de protección, primero a nivel teórico y después a nivel empírico. El estudio consta de dos partes, una primera descriptiva del perfil del menor desistente, y una segunda hecha con encuestas, donde se evalúan les dimensiones de la competencia emocional en un grupo de adolescentes infractores. A partir de una muestra de 288 adolescentes infractores, 86 reincidentes y 202 desistentes, de las comarcas del Baix Llobregat, Garraf, Alt Penedès y algunos municipios del Anoia, se analizan las diferencias sociodemográficas, criminológicas y del recorrido educativo hecho en la Dirección General de Justicia Juvenil. A continuación participan en el estudio por encuesta una muestra de 101 adolescentes, 45 reincidentes y 56 desistentes, procedentes de los programas de mediación, medio abierto e internamiento. Los adolescentes desistentes en el delito obtienen puntuaciones superiores a los reincidentes, siendo estas diferencias estadísticamente significativas en la dimensión de competencia social y en la puntuación total de competencia emocional.

Osteoprotegerin and bone mineral density in hemodiafiltration patients.

A newly identified cytokine, osteoprotegerin (OPG) appears to be involved in the regulation of bone remodeling. In vitro studies suggest that OPG, a soluble member of the TNF receptor family of proteins, inhibits osteoclastogenesis by interrupting the intercellular signaling between osteoblastic stromal cells and osteoclast progenitors. As patients with chronic renal failure (CRF) often have renal osteodystrophy (ROD), we investigated the role of osteoprotegerin (OPG) in ROD, and investigated whether there was any relationship between serum OPG, intact parathyroid (PTH) (iPTH), vitamin D, and trabecular bone. Serum OPG combined with iPTH might be a useful tool in the noninvasive diagnosis of ROD, at least in cases in which the range of PTH values compromises reliable diagnosis. Thirty-six patients on maintenance hemodiafiltration (HDF) and a control group of 36 age and sex matched healthy subjects with no known metabolic bone disease were studied. The following assays were made on serum: iPTH, osteocalcin (BGP), bone alkaline phosphatase, 25(OH)-cholecalciferol, calcium, phosphate, OPG, IGF-1, estradiol, and free testosterone. Serum Ca++, P, B-ALP, BGP, IGF-1, iPTH, and OPG levels were significantly higher in HDF patients than in controls, while DXA measurements and quantitative ultrasound (QUS) parameters were significantly lower. On grouping patients according to their mean OPG levels, we observed significantly lower serum IGF-1, vitamin D3 concentrations, and lumbar spine and hip bone mineral density in the high OPG groups. No correlation was found between OPG and bone turnover markers, whereas a negative correlation was found between serum OPG and IGF-1 levels (r=-0.64, p=0.032). Serum iPTH concentrations were positively correlated with bone alkaline phosphatase (B-ALP) (r=0.69, p=0.038) and BGP (r=0.92, p<0.001). The findings made suggest that an increase in OPG levels may be a compensatory response to elevated bone loss. The low bone mineral density (BMD) levels found in the high OPG group might have been due to the significant decrease in serum IGF-1 and vitamin D3 observed. In conclusion, the findings made in the present study demonstrate that increased OPG in hemodiafiltration patients is only partly due to decreased renal clearance. As it may partly reflect a compensatory response to increased bone loss, this parameter might be helpful in the identification of patients with a marked reduction in trabecular BMD.

Perfil da demanda por microcomputadores no Brasil: o que os microdados da POF-IBGE indicam?

Neste estudo, analisou-se a relação entre a despesa domiciliar com a compra de computadores e as características demográficas e socioeconômicas dos domicílios brasileiros. Foram utilizados os microdados de duas Pesquisas de Orçamentos Familiares (POF), elaboradas pelo Instituto Brasileiro de Geografia e Estatística (IBGE): 2002-2003 e 2008-2009. Essas bases permitiram que se utilizasse a despesa total per capita como variável definidora do poder aquisitivo do domicílio. Foi adotada uma abordagem econométrica para a natureza desse tipo de análise, isto é, o modelo de seleção de Heckman, que envolve dois estágios. No primeiro, analisaram-se os fatores associados à probabilidade de ocorrência da despesa e, no segundo, foram avaliados os fatores associados aos valores da despesa efetuada. Os principais resultados indicaram que o perfil do chefe (gênero e idade) e a composição dos domicílios e escolaridade dos moradores são fatores relevantes tanto para a decisão de gastar quanto para a decisão sobre o valor a ser gasto. A redução da elasticidade que relaciona as despesas com computador ao poder aquisitivo do domicílio (em 2002-2003 foi 0,56763, enquanto em 2008-2009 caiu para 0,41546) pode ser explicada pela queda no preço dos computadores e pelo aumento do poder de compra das famílias.
