Ítem Climate change effects in older people's health: A scoping review(Wiley, 2024) Montoro-Ramírez, Eva María; Parra-Anguita, Laura; Álvarez-Nieto, Carmen; Parra-Anguita, Gema; López-Medina, Isabel MaríaBackground: Climate change has serious consequences for the morbidity and mortal-ity of older adults.Objective: To identify the effects of climate change on older people's health.Methods: A scoping review was conducted following the Joanna Briggs Instituteguidelines and the PRISMA-ScR checklist. Quantitative research and reports from or-ganizations describing the effects of climate change on older people were selected.Results: Sixty-three full-text documents were selected. Heat and air pollution werethe two factors that had the most negative effects on cardiovascular and respiratorymorbidity and mortality in older people. Mental health and cognitive function werealso affected.Conclusions: Climate change affects several health problems in older individuals,especially high temperatures and air pollution. Nursing professionals must have thenecessary skills to respond to the climate risks in older adults. More instruments arerequired to determine nursing competencies on climate change and the health of thispopulation group.Ítem Daphne, la Naturaleza al Rescate: las SbN contra los contaminantes(2024-09-27) Jiménez-Melero, Raquel; López-Valcárcel, María Eugenia; Parra-Anguita, GemaDaphne, una niña interesada en el medioambiente y en la Ciencia, nos explica qué son las Soluciones Basadas en la Naturaleza y cómo estas nos pueden ayudar a retirar los fármacos de las aguas residuales. De una forma amena y sencilla, este cómic nos acerca el trabajo de los científicos y las científicas en la búsqueda de soluciones ante una de las principales crisis ambientales: la contaminación de las aguas. Esta pequeña pieza de divulgación científica se enmarca dentro del proyecto "Soluciones basadas en la Naturaleza frente a contaminantes emergentes: Protegiendo las aguas para la Transición Ecológica (NbSPRO-TE)" financiado por el Ministerio de Ciencia e Innovación en su convocatoria 2021 de «Proyectos de Transición Ecológica y Transición Digital» .Ítem Ecotoxicological assessment of the effects of fluoxetine on Daphnia magna based on acute toxicity, multigenerational reproduction effects, and attraction-repellence responses.(2023-01) Stremmel, Helmut; Weiss, Linda; Ramos-Rodríguez, Eloísa; Araújo, Cristiano; Parra-Anguita, GemaFluoxetine, a common pharmaceutical used as an antidepressant, is already considered potentially hazardous to biota due to its increasing use and detection in European, North American, and Asian rivers. We studied the effects of fluoxetine on Daphnia magna, as we hypothesized that fluoxetine might have harmful effects, short and long-term, at different levels: survival, behaviour, and reproduction (offspring production). We applied two different approaches: (i) a scenario at environmentally relevant concentrations (0.1–1.0 μg/L) and (ii) a scenario simulating a future worsening of contamination (1–800 μg/L) until the reach of lethal concentrations. In the former, we examined whether there are multigenerational effects on reproduction and on the avoidance/colonisation behaviour in previously exposed populations. In the latter, three responses were assessed: survival, avoidance behaviour and reproduction. We did not detect differences in the reproduction output of D. magna among the treatments over the three generations examined. Irrespective of the multigenerational treatment, D. magna colonised the environments with fluoxetine in a similar way. In the second scenario, we determined the lethal concentration for 50% of the population (96 h-LC50 = 365 μg/L), which, in spite of the toxic effect, was attractive to organisms during the avoidance tests (24 h); in fact, D. magna were attracted (no repellence) even to the highest concentrations of fluoxetine tested (800 μg/L). Lastly, in a 21-day chronic toxicity test the reproduction output of D. magna increased with higher concentrations of fluoxetine. This effect might be related to the fact that the organisms in the contaminated treatment began their first reproduction earlier, when compared to that in the control treatments. In conclusion, this study discusses an identified hazard for aquatic biota due to the fluoxetine attraction effect and a predictive assessment of the consequences expected if its indiscriminate use increases.Ítem Ecotoxicological study of agrochemicals' effects on plankton community structure and function(Jaén : Universidad de Jaén, 2015-02-20) Del-Arco-Ochoa, Ana-Isabel; Parra-Anguita, Gema; Universidad de Jaén. Departamento de Biología Animal, Vegetal y Ecología[ES] Actualmente, los límites legales de agroquímicos se basan principalmente en test de toxicidad de laboratorio que evalúan los efectos tóxicos en test de única especie y de un único compuesto. Sin embargo, hay dos limitaciones principales asociadas a este enfoque: a) la extrapolación de los efectos basados en indicadores a nivel de individuo a un contexto más complejo a nivel de ecosistema con poblaciones y comunidades, y b) los químicos no aparecen aislados en el medio ambiente, en consecuencia la mezclas se deberían ser estudiadas para entender mejor tanto los efectos directos como indirectos de los agroquímicos. Por tanto, dentro de este nicho científico inexplorado, esta tesis explora escenarios de mezclas de agroquímicos, de condiciones ecológicas y de sus interacciones. Con el objetivo de contribuir a una mejor comprensión de los efectos de los agroquímicos en los sistemas acuáticos centrándose en las comunidades planctónicas y bentónicas de humedales, este trabajo se centra en dos escenarios: escenario agroquímico (mezcla, frecuencia de pulsos y límites) y escenario ecológico (interacciones ecológicas: competición y niveles jerárquicos).Ítem Effects of climate change in the elderly’s health: a scoping review protocol.(BMJ, 2022) Montoro-Ramírez, Eva María; Parra-Anguita, Laura; Álvarez-Nieto, Carmen; Parra-Anguita, Gema; López-Medina, Isabel MaríaIntroduction Climate change is a global problem that affects human health, especially the most vulnerable groups, including the elderly. However, no scope review includes the perspective of institutions specialised in climate change and health and whose reports are the basis for policies orientated on the environmental health. Therefore, this study aims to identify these effects on older people health. The results will allow health professionals to have valuable information enabling them to provide quality care in meeting the demand that this situation is producing. Methods and analysis A scoping review of the relevant literature will be performed from 2008 to 2021. The Joanna Briggs Institute guidelines and the PRISMA- Scoping Review Extension checklist will be used. A peer- reviewed search will be conducted using the electronic databases Medline, Scopus, Cumulative Index to Nursing and Allied Health Literature, Cochrane, PsycINFO and Cuiden Plus between October and December 2021. Original quantitative studies and reports from official agencies on the effects of climate change on the elderly health in any health and geographical context will be included. Literature selection will be made by two reviewers. The table format used for data extraction will be reviewed by the review team and tested by two reviewers. Ethics and dissemination This study does not require approval by an ethics committee to be conducted. This article will result in the mapping of the direct and indirect effects of climate change on the health of the elderly. The results will be published in scientific journals to be accessible to health professionals in the creation of care plans for the elderly at climate risk.Ítem Not Only Toxic but Repellent: What Can Organisms' Responses Tell Us about Contamination and What Are the Ecological Consequences When They Flee from an Environment?(MDPI, 2020-12) Araújo, Cristiano; Laissaoui, Abdelmourhit; Silva, Daniel C.V.R.; Ramos-Rodríguez, Eloísa; González-Ortegón, Enrique; Espíndola, Evaldo L.G.; Baldó, Francisco; Mena, Freylan; Parra-Anguita, Gema; Blasco, Julián; López-Doval, Julio; Sendra, Marta; Banni, Mohammed; Moreno-Garrido, IgnacioThe ability of aquatic organisms to sense the surrounding environment chemically and interpret such signals correctly is crucial for their ecological niche and survival. Although it is an oversimplification of the ecological interactions, we could consider that a significant part of the decisions taken by organisms are, to some extent, chemically driven. Accordingly, chemical contamination might interfere in the way organisms behave and interact with the environment. Just as any environmental factor, contamination can make a habitat less attractive or even unsuitable to accommodate life, conditioning to some degree the decision of organisms to stay in, or move from, an ecosystem. If we consider that contamination is not always spatially homogeneous and that many organisms can avoid it, the ability of contaminants to repel organisms should also be of concern. Thus, in this critical review, we have discussed the dual role of contamination: toxicity (disruption of the physiological and behavioral homeostasis) vs. repellency (contamination-driven changes in spatial distribution/habitat selection). The discussion is centered on methodologies (forced exposure against non-forced multi-compartmented exposure systems) and conceptual improvements (individual stress due to the toxic effects caused by a continuous exposure against contamination-driven spatial distribution). Finally, we propose an approach in which Stress and Landscape Ecology could be integrated with each other to improve our understanding of the threat contaminants represent to aquatic ecosystems.
