This paper analyses the impact of a series of managerial and organisational factors on occupational injuries. These consist of occupational safety measures, as regards both the intensity and the orientation of risk prevention in companies, and the adoption of certain work organisation practices, quality management and the use of flexible production technologies. We estimate a negative binomial regression based on a sample of 213 Spanish industrial establishments, defining a constant random parameter to take account of non-observable heterogeneity. Our results show that occupational safety measures, the intensive use of quality management tools and the empowerment of workers all help to reduce the number of injuries. We have also confirmed the presence of synergies between the organisational factors analysed and the development of an occupational safety strategy featuring participation and the extension of prevention to all levels of the organisation.

Blunt chest traumas are a clinical challenge, both for diagnosis and treatment. The use ofCardiovascular Magnetic Resonance can play a major role in this setting. We present two cases: a12-year-old boy and 45-year-old man. Late gadolinium enhancement imaging enabled visualizationof myocardial damage resulting from the trauma.

The combined action of nisin and lactacin F, two bacteriocins produced by lactic acid bacteria, is additive. In this report, the basis of this effect is examined. Channels formed by lactacin F were studied by experiments using planar lipid bilayers, and bactericidal effects were analyzed by flow cytometry. Lactacin F produced pores with a conductance of 1 ns in black lipid bilayers in 1 mM KClat 10 mV at 20°C. Pore formation was strongly dependent on voltage. Although lactacin F formed pores at very low potential (10 mV), the dependence was exponentialabov e 40 mV. The injuries induced by nisin and lactacin F in the membranes of Lactobacillus helveticus produced different flow cytometric profiles. Probably, when both bacteriocins are present, each acts separately; their cooperation may be due to an increase in the number of single membrane injuries

Background: Neonatal brain injuries are the main cause of visual deficit produced by damage to posterior visual pathways.While there are several studies of visual function in low-risk preterm infants or older children with brain injuries, research in children of early age is lacking. Aim: To assess several aspects of visual function in preterm infants with brain injuries and to compare them with another group of low-risk preterm infants of the same age. Study design and subjects: Forty-eight preterm infants with brain injuries and 56 low-risk preterm infants. Outcome measures: The ML Leonhardt Battery of Optotypes was used to assess visual functions. This test was previously validated at a post-menstrual age of 40 weeks in newborns and at 30-plus weeks in preterm infants. Results: The group of preterminfants with brain lesions showed a delayed pattern of visual functions in alertness, fixation, visual attention and tracking behavior compared to infants in the healthy preterm group. The differences between both groups, in the visual behaviors analyzed were around 30%. These visual functions could be identified from the first weeks of life. Conclusion: Our results confirm the importance of using a straightforward screening test with preterminfants in order to assess altered visual function, especially in infants with brain injuries. The findings also highlight the need to provide visual stimulation very early on in life.

In automobile insurance, it is useful to achieve a priori ratemaking by resorting to gene- ralized linear models, and here the Poisson regression model constitutes the most widely accepted basis. However, insurance companies distinguish between claims with or without bodily injuries, or claims with full or partial liability of the insured driver. This paper exa- mines an a priori ratemaking procedure when including two di®erent types of claim. When assuming independence between claim types, the premium can be obtained by summing the premiums for each type of guarantee and is dependent on the rating factors chosen. If the independence assumption is relaxed, then it is unclear as to how the tari® system might be a®ected. In order to answer this question, bivariate Poisson regression models, suitable for paired count data exhibiting correlation, are introduced. It is shown that the usual independence assumption is unrealistic here. These models are applied to an automobile insurance claims database containing 80,994 contracts belonging to a Spanish insurance company. Finally, the consequences for pure and loaded premiums when the independence assumption is relaxed by using a bivariate Poisson regression model are analysed.

L'elevada freqüència de victimització en nens, nenes i adolescents és una realitat que ha impulsat l’aparició de la denominada victimologia del desenvolupament, en la qual s’emmarca aquest projecte. Des d’aquesta perspectiva, s’han entrevistat 123 joves, d’entre 12 i 17 anys (M= 14,28 i DT= 1,43) atesos en 13 centres de salut mental de la província de Barcelona, sobre les seves experiències de victimització relatives a delictes comuns, victimització per part de cuidadors, victimització per iguals i/o germans, victimització sexual, victimització indirecta/ser testimoni i victimització per Internet. Alhora s’han avaluat les característiques i el perfil dels victimaris, així com el malestar psicològic i la presència de psicopatologia en les víctimes. Un 99,2% dels menors ha patit alguna forma de victimització al llarg de la seva vida i un 85,4% l’ha sofert en el darrer any. Gran part de les victimitzacions s’inicien durant la infància, estan vinculades a persones conegudes, de l’entorn habitual del menor, i són comeses per un agressor de sexe masculí. Si bé no totes aquestes formes de victimització suposen delictes punibles al nostre país, sí que configuren una part important de la biografia del menor que cal considerar i valorar, donades les implicacions que poden arribar a tenir en el seu desenvolupament. Els resultats confirmen que la victimització i, especialment, l’acumulació d’experiències victimitzants tenen un efecte negatiu en l’estat emocional del menor, cosa que fa que, en els adolescents polivictimitzats, s’obtinguin nivells més elevats de psicopatologia general, així com de simptomatologia internalitzant i externalitzant.

Les ferides cròniques, especialment les de lenta curació, suposen una carga important pels pacients i pels sistemes de salut. És imprescindible investigar en nous tractaments que redueixin el temps de curació d‟aquestes ferides. L‟objectiu d‟aquest projecte, és avaluar l‟eficàcia dels factors de creixement, obtinguts de plasma ric en plaquetes, en la curació o millora de les ferides cròniques. El projecte s‟ha dissenyat com un estudi d‟una sèrie de casos que compara el tractament convencional amb el tractament amb factors de creixement. La variable resultats és la curació o la disminució del àrea de l‟úlcera. El projecte pretén avaluar uns quants pacients consecutius atesos en l‟ unitat de ferides cròniques del nostre hospital. Els subjectes del estudi han de presentar una ferida de més de 3 mesos d‟evolució nul·la o escassa resposta als tractaments habituals. La tècnica de obtenció dels factors de creixement plaquetar no és complexa i es pot realitzar en l‟entorn d‟un hospital de dia. No s‟han comunicat en la literatura efectes secundaris majors de l‟aplicació dels factors de creixement en ferides cròniques.
