Efecto agudo hipotensivo de la combinación de ejercicios basados en caminar y de resistencia en mujeres mayores de 65 años no institucionalizadas

Under a Creative Commons license.[EN]: [Objective]: The aim of this study was to test the effects on blood pressure of a single bout of low-intensity resistance exercise combined with moderate aerobic walk-based exercise performed by active, controlled hypertensive elderly women. [Method]: Forty-two participants were randomized in two types of sessions: exercise session (n = 21), that performed a single bout of combined exercise and control session (n = 21) that keep in rest during the bout. Pre-session, post-session and post-24-hour systolic, diastolic and mean pressure values were evaluated and compared between groups. [Results]: Statistical significant reductions were achieved just after the performed bout (7% of reduction) and 24 hours after the bout (9% of reduction) on the diastolic blood pressure values in the exercise session group. [Conclusions]: In this population, a single bout of combined session is feasible and safe and has a hypotensive effect on diastolic blood pressure in both immediately and after 24 hours post exercise.[ES]: [Objetivo]: Comprobar el efecto hipotensivo que una sola sesión de ejercicio combinado puede tener sobre la presión arterial de mujeres hipertensas controladas y mayores de 65 años.

Death, dying and informatics: misrepresenting religion on MedLine

BACKGROUND: The globalization of medical science carries for doctors worldwide a correlative duty to deepen their understanding of patients' cultural contexts and religious backgrounds, in order to satisfy each as a unique individual. To become better informed, practitioners may turn to MedLine, but it is unclear whether the information found there is an accurate representation of culture and religion. To test MedLine's representation of this field, we chose the topic of death and dying in the three major monotheistic religions. METHODS: We searched MedLine using PubMed in order to retrieve and thematically analyze full-length scholarly journal papers or case reports dealing with religious traditions and end-of-life care. Our search consisted of a string of words that included the most common denominations of the three religions, the standard heading terms used by the National Reference Center for Bioethics Literature (NRCBL), and the Medical Subject Headings (MeSH) used by the National Library of Medicine. Eligible articles were limited to English-language papers with an abstract. RESULTS: We found that while a bibliographic search in MedLine on this topic produced instant results and some valuable literature, the aggregate reflected a selection bias. American writers were over-represented given the global prevalence of these religious traditions. Denominationally affiliated authors predominated in representing the Christian traditions. The Islamic tradition was under-represented. CONCLUSION: MedLine's capability to identify the most current, reliable and accurate information about purely scientific topics should not be assumed to be the same case when considering the interface of religion, culture and end-of-life care

Analysis of the mechanical properties of wood attacked by Xylotrechus arvicola (Coleoptera: Cerambycidae) larvae, and its influence on the structural properties of the plant

Xylotrechus arvicola is an invasive insect on Vitis vinifera in the main wine-producing regions of the Iberian Peninsula. X. arvicola larvae bore into the grapevine wood and make galleries, which cause structural damages to the plant. The aim of this study was to investigate how grapevine wood infested by larvae affects the mechanical properties of the plant in comparation with those of uninfested wood. Samples of grapevine wood uninfested and infested by larvae were collected from vineyards. Compression and flexural strengths as well as simulated structures of grapevine wood in field, in relation to harvest weight by variety, were used to quantify the wood mechanical properties. Infested wood endured a lower strength and normal tension, and exhibited a reduction in the structural capacities in the simulation of harvest weight of 'Cabernet-Sauvignon' variety (up to 62.0 %). 'Tempranillo' (despite its high mechanical slenderness values) and 'Cabernet-Sauvignon', were the varieties that showed a higher resistance on trunks and branches, respectively. A lower bending moment was observed on the infested branches of all varieties. Changes in the mechanical properties of infested wood suggest a decrease in mechanical resistance of wood attacked by larvae that could contribute to the rupture of the infested grapevine over time. Grapevine wood attacked by X. arvicola larvae could be more sensitive to mechanical external factors in vineyards such as strong winds, harvest weight and vibration exerted by harvesting machines

Influence of functional capacity on lipid profile, muscle damage and biochemical profile among community-dwelling elderly-people

Under a Creative Commons license.[ES]: [Objetivo]: Describir la influencia que la capacidad funcional tiene sobre el perfil bioquímico y daño muscular, así como analizar la relación existente entre estas variables en personas mayores no institucionalizadas. [Método]: Se utilizó un diseño de corte transversal-observacional en el que se incluyeron 43 sujetos (19 hombres y 24 mujeres). Se analizó la capacidad funcional (T6MW, TUG, CST y PM) y variables bioquímicas (colesterol total, HDL, LDL, triglicéridos, glucosa, GOT, GPT, creatinina y CK). Se establecieron diferencias en función del nivel de capacidad funcional de cada una de las pruebas, así como las relaciones entre cada una de las variables. [Resultados]: Los sujetos que obtuvieron mayores niveles en los test de capacidad funcional obtuvieron resultados más satisfactorios para las diferentes variables de estudio bioquímico (p < 0,05). Estas diferencias se mantuvieron también cuando los datos fueron analizados atendiendo al género. Además, se observó una correlación entre el daño muscular y las diferentes variables de capacidad funcional testadas. [Conclusión]: Este estudio muestra la influencia que la capacidad funcional en mayores presenta sobre parámetros bioquímicos asociados a enfermedades metabólicas o cardiovasculares, así como sobre el daño muscular y sugiere la necesidad de implementar actividades tanto aeróbicas como de fuerza en población mayor.[EN]: [Objective]: To analyze the influence of functional capacity on the biochemical profile and muscle damage and to test the level of relationship between these variables among community-dwelling elderly people. [Method]: A cross-sectional, observational study with 43 participants (19 males and 24 women) was performed. Functional capacity (including 6MWT, TUG test, CST test and Hand grip strength test), and biochemical profile (including total cholesterol, HDL, LDL, triglycerides, glucose, GOT, GPT, creatine and CK) were assessed. Differences on biochemical profile-related variables regarding the functional capacity level were analyzed. The level of relationship between the variables comprising these two domains was also assessed. [Results]: Those participants with a better results in functional capacity variables also achieved the better results in regard of the biochemical parameters measured (p < 0,05). These differences were also maintained after a gender-based analysis. Moreover, relationships between muscle damage and functional capacity variables were also achieved. [Conclusion]: This study shows the influence of the functional capacity on the biochemical parameters (mostly associated to cardiovascular and metabolic diseases) along with the influence that such variables have on the muscle damage and suggest the needed on the implementation of both aerobic and strength training for elderly.El presente trabajo ha sido financiado por la Junta de Andalucía.

Condiciones de formación de Paligorskita-Sepiolita en litofacies dolomíticas de la cubeta de Piedrabuena. Campo de Calatrava (Ciudad Real)

Mineralogical, textural and chemical features of two drilling cores that cross over dolomite marls and green clays from Piedrabuena basin (Campo de Calatrava, Central Spain), are studied. The experimental results let us to stablish three stages showing a shallow lacustrine environment with climatic and tectonic changes: a) Lower stage (drying). Massive dolomicrites with increasing- desiccation features at topo Mineralogical association: dolomite-phyllosilicates (sepiolite-palygorskite-illite). b) Middle stage (expansive-retractive). Dolomicrites and intradolomicrites, sometimes bearing clasts, with early dedolomitization textures. Mineralogical association: dolomite-phyllosilicates (palygorskite-sepiolite-illite-dioctahedral smectite)-calcite-quartz. c) Upper stage (freshening). Dolomicrites witb calcite related to dedolomitization processes and thin clay layers witb clasts (quartz, quartzite, mica and carbonates). Mineralogical association: dolomite-ealcite-phyllosilicates (palygorskite-illite-dioctahedral smectite-kaolinite)-quartz. Illite, dioctahedral smectite and kaolinite show a clearly detrital origin from surrounding materials (Palaeozoic quartzites and slates), whilst palygorskite and sepiolite origin is related with early diagenetic processes. So, sepiolite in dolomicrites is associated to desiccation conditions and palygorskite seems have been Cormed after alteration of precursor phases, dioctahedral smectite mainly, under floods conditions. Moreover, both sepiolite and palygorskite show a relation among their genesis, amorpbous silica contents (up to 5.5%), and dedolomitization processes, in a Mgrich environmenl.Se estudian en este trabajo las características mineralógicas, texturales y químicas de las margas dolomicríticas y lutitas verdes, en la cubeta de Piedrabuena (Ciudad Real). Los resultados experimentales obtenidos permiten establecer tres episodios que reflejan un ambiente lacustre somero con cambios climáticos y tectónicos: a) Episodio inferior (desecación). Dolomicritas masivas con rasgos de desecación que se incrementan a techo. Asociación mineralógica: dolomita-filosilicatos (sepiolita-paligorskita-ilita). b) Episodio medio (expansivo-retractivo). Dolomicritas e intradolomicritas ocasionalmente conteniendo clastos, con texturas incipientes de dedolomitización. Asociación mineralógica: dolomitafilosilicatos (paligorskita-sepiolita-ilita-esmectita dioctaédrica)-ealcita-cuarzo. c) Episodio superior (endulzamiento). Dolomicritas con calcita resultado de procesos de dedolomitización y finas láminas lutíticas con clastos (cuarzo, cuarcita, mica y carbonatos). Asociación mineralógica: dolomita-ealcita-filosilicatos (paligorskita-ilita-esmectita dioctaédrica-eaolinita)cuarzo. La ilita, esmectita dioctaédrica y caolinita, muestran un claro origen detrítico a partir de los materiales que rodean la cubeta (cuarcitas y pizarras paleozoicas), mientras que el origen de la paligorskita y sepiolita se relaciona con procesos de diagénesis temprana. Así, la sepiolita en las dolomicritas se asocia a procesos de desecación, mientras que la paligorskita parece haberse formado tras la alteración de fases precursoras, esmectita dioctaédrica fundamentalmente, tras episodios de aportes. Además, tanto la sepiolita como la paligorskita muestran una clara relación entre su génesis, contenidos en sílice amorfa (hasta un 5,5%) y los procesos de dedolomitización, en un medio con alto contenido en Mg2+ (aq.)

Evolutionary-based prediction interval estimation by blending solar radiation forecasting models using meteorological weather types

Recent research has shown that the integration or blending of different forecasting models is able to improve the predictions of solar radiation. However, most works perform model blending to improve point forecasts, but the integration of forecasting models to improve probabilistic forecasting has not received much attention. In this work the estimation of prediction intervals for the integration of four Global Horizontal Irradiance (GHI) forecasting models (Smart Persistence, WRF-solar, CIADcast, and Satellite) is addressed. Several short-term forecasting horizons, up to one hour ahead, have been analyzed. Within this context, one of the aims of the article is to study whether knowledge about the synoptic weather conditions, which are related to the stability of weather, might help to reduce the uncertainty represented by prediction intervals. In order to deal with this issue, information about which weather type is present at the time of prediction, has been used by the blending model. Four weather types have been considered. A multi-objective variant of the Lower Upper Bound Estimation approach has been used in this work for prediction interval estimation and compared with two baseline methods: Quantile Regression (QR) and Gradient Boosting (GBR). An exhaustive experimental validation has been carried out, using data registered at Seville in the Southern Iberian Peninsula. Results show that, in general, using weather type information reduces uncertainty of prediction intervals, according to all performance metrics used. More specifically, and with respect to one of the metrics (the ratio between interval coverage and width), for high-coverage (0.90, 0.95) prediction intervals, using weather type enhances the ratio of the multi-objective approach by 2%¿. Also, comparing the multi-objective approach versus the two baselines for high-coverage intervals, the improvement is 11%¿% over QR and 10%¿% over GBR. Improvements for low-coverage intervals (0.85) are smaller.The authors are supported by projects funded by Agencia Estatal de Investigación, Spain (PID2019-107455RB-C21 and PID2019-107455RB-C22/AEI/10.13039/501100011033).
