New approaches to Mediterranean fluvial communities

The organization of fluvial benthic communities in the Iberian Mediterranean system shows a series of factors which differ in part from present models suggested in the current literature. The effects of disturbances can be observed in models including the gradient of organization (WARD & STANFORD, 1 983; VANNOTE et al. , 1 980; SABATER et al, . in press) in the major and permanent northwest basins, but not in temporary systems. Temporality does usual1y not represent a handicap as far as the organization of the algae communities and the macroinvertebrates communities is concemed,: equivalent diversities have been observed in temporary and permanent systems. But a latitudinal gradient is observed among the temporary systems, with an increment to the south of the diversity. Mediterranean fluvial systems have integrated floods as periodical perturbations in the dynamics of benthic communities, which have a high resistance to flood-related disturbance and a high subsequent resilience.The organization of fluvial benthic communities in the Iberian Mediterranean system shows a series of factors which differ in part from present models suggested in the current literature.

Trends in adult asthma hospitalization: gender-age effect

BACKGROUND: Hospital admissions due to asthma are a reliable source of information on the morbidity of the disease which, after the increase observed in the last quarter of the last century, shows a declining trend in the last few years. The aim of this study was to look at hospital admission trends due to asthma in our community and analyze some of its associated factors. METHODS: Retrospective analysis of all hospital admissions involving adults aged 15 years and older with asthma as the primary or secondary diagnosis (if the first diagnosis was respiratory failure or respiratory infection) in Public Health Service hospitals in the Galician region of Spain between the years 1995-2009 (total 24,766 admissions). RESULTS: The majority of patients admitted were female (71%), over 60 years of age (64%), and admission occurred predominantly in the winter months. The hospitalization rate due to asthma tripled over the period studied, this being mainly accounted for by women aged over 60 years. Mean hospital stay was 9.2 days, longer in older patients or those admitted over the weekend. CONCLUSIONS: A significant increase in hospital admissions due to asthma over the last few years has been observed in our community, mainly involving older women. The mean stay seems long, increasing with patients' age and admission over the weekend

Clinical Prognosis of Right-Sided Infective Endocarditis not Associated with Cardiac Devices or Intravenous Drug use : a Cohort Study and Meta-Analysis

Right-sided infective endocarditis (RSIE), classically associated with intravenous drug use or intracardiac devices, is considered a good-prognosis infective endocarditis (IE) form. However, predisposing factors and prognosis for "NODID" RSIE (NOt associated with cardiac Devices or Intravenous Drug use) remain unclear. The aim of this study was to evaluate predisposing factors and prognosis of NODID RSIE compared to other RSIE forms. A retrospective cohort study (January 2008-January 2019) was conducted in a reference center on 300 patients diagnosed with IE. Endocarditis-related events were defined as related to IE in mortality or open-heart surgery during follow-up. A review and meta-analysis of associated literature (January 2008-January 2019) were also performed. Fifty-seven patients presented RSIE (19%), 22 of which were NODID RSIE (39%). Use of intravascular catheters (23% vs 3%; p = 0.027) and congenital heart diseases (18% vs 0%; p = 0.019) were associated with NODID RSIE. This group had a higher in-hospital mortality (23% vs 3%; p = 0.027) and endocarditis-related event rates (41% vs 6%; p = 0.001) than non-NODID RSIE. Furthermore, NODID RSIE was independently associated with in-hospital endocarditis-related events (OR = 19.29; 95%CI:2.23-167.16; p = 0.007). Our meta-analysis evaluated four studies and identified 96 cases (30%) of NODID RSIE from 320 total RSIE cases. NODID RSIE patients demonstrated higher in-hospital mortality (RR = 2.81; 95%CI:1.61-4.90; p < 0.001; I = 0.0%) and necessity of open-heart surgery (RR = 13.89; 95%CI:4.14-46.60; p < 0.001; I = 0.0%) than non-NODID RSIE cases. Our study suggests that NODID RSIE has the highest endocarditis-related event rate and in-hospital mortality among RSIE cases and therefore should not be considered a good-prognosis IE

Yacimientos sin estratigrafía: Devesa do Rei, ¿un sitio cultual de la Prehistoria reciente y la Protohistoria de Galicia?

In this text we explore a singular site that offers a series of important novelties, both in terms of its discontinuous pattern of use in different periods (covering a lengthy period from the Neolithic to the Iron Age), and its apparent use for ritual purposes in all of them, as well as the possible identification of a funerary structure from the Galician Iron Age. At the same time, this work is proposed as a case for study that makes it possible to define a procedure to reconstruct the sequence and function of open sites from Late Prehistory in Galicia characterized by a lack of vertical stratigraphy. This problem is solved by combining different analytical techniques, all based on a record of high quality excavation that makes use of analyses of material culture, radiocarbon dating, distribution patterns, as well as soil and sediment analysis.Se estudia en este texto un yacimiento singular que ofrece importantes novedades, tanto por su reocupación discontinua en épocas distintas (con una secuencia amplia que cubre desde el Neolítico a la Edad del Hierro), como por su aparente funcionalidad ritual en todas ellas, y la posible identificación de una estructura funeraria de la Edad del Hierro de Galicia. Al mismo tiempo, este trabajo se plantea como caso de estudio que permite definir un procedimiento para reconstituir la secuencia y función de yacimientos abiertos de la Prehistoria Reciente de Galicia caracterizados por no presentar estratigrafía vertical. Este problema se solventa con el entrecruzamiento de diferentes técnicas de análisis basadas todas ellas en un registro de excavación de calidad que se sirve de análisis de cultura material, radiocarbónicos, distributivos, sedimentológicos y edafológicos
