    Treatment of paediatric burns with a nanocrystalline silver dressing compared with standard wound care in a burns unit: A cost analysis

    Burns are a leading cause of non-natural death in South African infants and children. Conventional care of partial-thickness burns often requires painful, time consuming and costly twice-daily dressing changes to clean the wound and apply antimicrobial topical agents. A new topical nanocrystalline silver-coated (NS) dressing (Acticoat; Smith & Nephew) has been developed and is the first-line treatment of choice in many burn centres. However, because of its cost the Department of Health has been reluctant to introduce it as a standard of care. We retrospectively studied 4 randomly selected paediatric burn patients, calculating the cost associated with the use of NS dressings and comparing this with the projected costs of three previously standard burn wound treatment regimens. NS dressings were changed every 3 days based on their sustained and slow release of silver ions over 72 hours. Using NS clearly saved costs compared with the three other regimens. The demonstrated cost savings resulted primarily from the decreased number of dressings, and the presumed shorter hospital stay

    Happiness as stable extraversion : internal consistency reliability and construct validity of the Oxford Happiness Questionnaire among undergraduate students

    The Oxford Happiness Questionnaire (OHQ) was developed by Hills and Argyle (2002) to provide a more accessible equivalent measure of the Oxford Happiness Inventory (OHI). The aim of the present study was to examine the internal consistency reliability, and construct validity of this new instrument alongside the Eysenckian dimensional model of personality. The Oxford Happiness Questionnaire was completed by a sample of 131 undergraduate students together with the abbreviated form of the Revised Eysenck Personality Questionnaire. The data demonstrated good internal consistency reliability (alpha = .92) and good construct validity in terms of positive association with extraversion (r = .38 p < .001) and negative association with neuroticism (r = −.57 p < .001). The kind of happiness measured by the OHQ is clearly associated with stable extraversion

    Private Financing or Not, That is the Question: Lessons from the Light Rail Systems in Spain

    The objective of this paper is to analyze if there is any difference between the light rail systems in Spain according to whether they have been carried out through public financing or private financing (totally or partially). The importance of this study lies in the fact that, for decades, the public–private partnership has been proposed as an alternative to public financing of public transport projects in order to obtain additional financial resources, reduce the public deficit, and increase efficiency. However, there are hardly any detailed studies describing how these initiatives have turned out. Therefore, the present study analyzes if there is any difference in the main variables explaining the performance of light rail projects in Spain depending on their source of funding can be found. For this, the relationship between variables related to design, operation and costs of the projects, and the percentage of private financing were statistically analyzed. As the most relevant conclusion, we underline the fact that the investment per passenger increases when financing is completely private. This would indicate that the most cost-effective lines, from a social standpoint, were financed totally or partially by the public administrations, whereas the least beneficial ones for society were assigned to private enterprises. This finding provides an advance in the knowledge of the consequences of private participation in the financing of public transport projects, indicating, moreover, that the biggest beneficiaries of this type of projects might be the construction companies and the politicians involvedThe authors would like to thank the ERDF of European Union for financial support via project ‘‘Herramienta para la evaluacio´n previa de infraestructuras de transporte pu´blico’’ (GGI3003IDIE). We also thank to Public Works Agency and Regional Ministry of Public Works and Housing of the Regional Government of Andalusia (AOPJA) and the Ministry of Education, Culture and Sports of the Government of Spain

    Strategic green infrastructure planning in Germany and the UK: a transnational evaluation of the evolution of urban greening policy and practice

    Get PDF
    The evolution of Green Infrastructure (GI) planning has varied dramatically between nations. Although a grounded set of principles are recognized globally, there is increasing variance in how these are implemented at a national and sub-national level. To investigate this the following paper presents an evaluation of how green infrastructure has been planned for in England and Germany illustrating how national policy structures facilitate variance in application. Adopting an evaluative framework linked to the identification of GI, its development and monitoring/ feedback the paper questions the impacts on delivery of intersecting factors including terminology, spatial distribution and functionality on effective GI investment. This process reviews how changing policy structures have influenced the framing of green infrastructure policy, and subsequent impact this has on the delivery of green infrastructure projects

    Carcinogen-induced pancreatic lesions in the mouse:effect of Smad4 and Apc genotypes

    No full text
    Mutations in the tumour suppressor genes SMAD4 (DPC4, deleted in pancreatic cancer locus 4) and adenomatous polyposis coli (APC) have been implicated in the development of pancreatic cancer in humans. Treatment of wild-type, Smad4(+/-), Apc(Min/+) or Apc(Min/+)Smad4(+/-) mice with N-Nitroso-N-Methyl Urea (NMU) results in abnormal foci in pancreatic acinar cells characterized by increased levels of beta-catenin. Previously such foci have been shown to be the precursors of pancreatic neoplasia. Interestingly, only NMU-treated Apc(Min/+)Smad4(+/-) mice exhibit a significant increase in abnormal pancreas, which was found to be due to increased number of abnormal foci rather than increased focus size. A range of foci sizes were analysed, but only smaller abnormal foci were characterized by morphological nuclear atypia. These studies suggest functional co-operation between TGF-beta and Wnt signalling pathways in the suppression of pancreatic tumorigenesis in the mouse
