Indización y uso de los Descriptores MeSH en Hospitalización a Domicilio
2017
Objetivo: Analizar la utilización de los Descriptores, como Major Topic, en la indización de los artículos sobre Hospitalización Domiciliaria en la base de datos MEDLINE.Método: Estudio descriptivo transversal de los registros de indización recogidos en la base de datos MEDLINE (vía PubMed) hasta 2016. El término utilizado, como descriptor principal para la búsqueda fue «Home Care Services, Hospital-Based».El método de muestreo fue la aleatorización simple sin reemplazo, tomando como base el número total de referencias obtenidas (tamaño muestral 386).Resultados: Se observaron diferencias significativas en la utilización de los Descriptores asociados a hospitalización a domicilio. La compara…
Technological differences and convergence in the OECD
2000
Abstract. In this paper we test the homogeneity of the technological parameters among OECD countries, which is the maintained hypothesis in most of the empirical growth literature. We first identify differences in the constant term of the convergence equation estimated for the OECD 1960/1990 sample using a fixed- effects estimator. Then we provide a formal test of the homogeneity of technological parameters across groups of countries. We identify at least two different groups within the OECD, with significantly different technologies. Convergence within each group is fast, supporting the notion of club convergence. Nevertheless, the implausible parameter values obtained for the leading tech…
Comparative Investigation on the Nutrient Composition of Healthy and Injured Spruces of Different Locations
1988
Investigations on the content of cations (Ca2+, K+, Mg2+ and Mn2+) were carried out in spruce trees at two exemplary locations in the Taunus montains (Konigstein) and in the Hunsruck mountains (Hattgenstein) in the course of the vegetation period in 1985 and 1986.
Regulation of Rooting Ability of Solanum tuberosum L. Explants by Gaseous Environment, In Vitro
1997
It has been reported by many investigators that morphogenesis of expiant tissue can be regulated by the composition of the nutrient medium as well as by the gaseous environment (Buddendorf-Joosten and Woltering, 1994). The aim of the present study was to investigate different effects on rooting ability of potato expiants in vitro, caused by limited gas exchange and IBA and BAP treatment.
Database to Ontology Mapping Patterns in RDB2OWL Lite
2016
We describe the RDB2OWL Lite language for relational database to RDF/OWL mapping specification and discuss the architectural and content specification patterns arising in mapping definition. RDB2OWL Lite is a simplification of original RDB2OWL with aggregation possibilities and order-based filters removed, while providing in-mapping SQL view definition possibilities. The mapping constructs and their usage patterns are illustrated on mapping examples from medical domain: medicine registries and hospital information system. The RDB2OWL Lite mapping implementation is offered both via translation into D2RQ and into standard R2RML mapping notations.
Association between use of novel glucose-lowering drugs and COVID-19 hospitalization and death in patients with type 2 diabetes: a nationwide registr…
2022
Abstract Aims Type 2 diabetes (T2DM) in patients with coronavirus disease-19 (COVID-19) is associated with a worse prognosis. We separately investigated the associations between the use of sodium-glucose cotransporter 2 inhibitors (SGLT2i), glucagon-like peptide-1 receptor agonists (GLP-1 RA), and dipeptidyl peptidase-4 inhibitors (DPP-4i), and the risk of COVID-19 hospitalization and death. Methods and results Patients with T2DM registered in the Swedish National Patient Registry and alive on 1 February 2020 were included. ‘Incident severe COVID-19’ was defined as the first hospitalization and/or death from COVID-19. A modified Poisson regression approach was applied to a 1:1 propensity sc…
Housekeepers in France: Cinderella in the shadow
2006
Référence interne : 06054; This report is addressed as a story from three different angles: How have competitive economical, technical and social conditions, critical events, changed in the hotel industry? What is housekeeper job quality really like, is it temporary job or sideline with no prospects for a captive labor force? How have firms' strategies affected the quality of work, in terms of working conditions and career ladders, for example depending on the choice of directly managing or subcontracting room cleaning?
Domestic pig prioritized in one health action against fascioliasis in human endemic areas: Experimental assessment of transmission capacity and epide…
2021
The Northern Bolivian Altiplano is the human fascioliasis hyperendemic area where the highest prevalences and intensities in humans have been reported. Preventive chemotherapy was implemented in the last ten years. Surveillance showed high human infection and re-infection rates in between the annual triclabendazole monodose treatments. A complementary One Health control action was launched to decrease the infection risk. Among the multidisciplinary axes, there is the need to establish animal reservoir species priorities for a more efficient control. Laboratory and field studies were performed for the first time to assess the Fasciola hepatica transmission capacity of the pig and its potenti…
The Role of Micronutrients in Human Papillomavirus Infection, Cervical Dysplasia, and Neoplasm
2023
There is evidence that diet and nutrition are modifiable risk factors for several cancers. In recent years, attention paid to micronutrients in gynecology has increased, especially regarding Human papillomavirus (HPV) infection. We performed a review of the literature up until December 2022, aiming to clarify the effects of micronutrients, minerals, and vitamins on the history of HPV infection and the development of cervical cancer. We included studies having as their primary objective the evaluation of dietary supplements, in particular calcium; zinc; iron; selenium; carotenoids; and vitamins A, B12, C, D, E, and K. Different oligo-elements and micronutrients demonstrated a potential prote…
