    The human population is increasing due to lengthening life expectancy, but the quality of life and health of people is moving in the opposite direction. The purpose of this study is to evaluate how aquatic resistance interval training can influence body composition, body image perception and adherence to the Mediterranean diet (MD) in older women participants in a nutrition education program and to study the relation between these variables. Thirty-four participants aged 69 ± 4 years were randomly assigned into two groups: experimental (aquatic resistance interval training plus nutritional intervention) and control (nutritional intervention). The intervention consisted of resistance training in an aquatic environment carried out for 14 weeks (three sessions per week; 60 min each). Body composition, body image perception and adherence to MD diet were evaluated at baseline and 14 weeks. No significant differences were found between groups regarding body image perception and adherence to the MD. There was a significant increase in muscle mass (kg) (p < 0.001) and a significant decrease in fat mass (kg) (p < 0.001) in the intervention group when compared to the control group. The addition of aquatic resistance interval training to a nutritional intervention was not sufficient to change body image perception and adherence to MD but produced improvement in body composition (through an increase in muscle mass and decrease on fat mass) in older women

    Un estudio cualitativo sobre los diferenciales de género en la educación superior: percepciones de las académicas en contextos masculinizados

    El contexto universitario refleja, al igual que la sociedad en general, la falta de equidad y equilibrio en la representación de mujeres y hombres. En la academia aún encontramos una alta presencia de hombres, especialmente, en lo que respecta a las cátedras universitarias. En este estudio presentamos y analizamos resultados de un proyecto de investigación desarrollado en la Universidad de Alicante (España). Del análisis realizado en los siete centros o unidades académicas de esta universidad, en el que aún las académicas conviven en contextos masculinizados, emergen las diferencias de oportunidades percibidas por las profesoras universitarias en su desarrollo profesional docente e investigador, aunque muchas de ellas no las relacionan con la discriminación por género. Cuando las académicas se han encontrado en situaciones discriminatorias manifiestan una actitud activa y reivindicativa, excepto en los centros altamente masculinizados donde mantienen una actitud pasiva para que el ambiente de trabajo sea óptimo. Consideramos que es necesario continuar indagando en estos espacios donde la presencia de las académicas sigue siendo minoritaria a pesar de las reformas universitarias en materia de igualdad desarrolladas en la Educación Superior

    [Abstract] Introduction. The prevalence of COPD phenotypes that are referred for assessment for lung transplantation is unknown, as well as whether specific phenotype influences post-transplant evolution in those patients who receive it. Material and methods. Ambispective observational study without intervention. The main objective was to know the prevalence of the different COPD phenotypes of the patients referred for the evaluation of a lung transplant. Secondary objective were to compare their clinical characteristics, to perform an analysis of post-transplant survival or complications according to their phenotype. Results. 502 patients were evaluated for lung transplantation, of which 173 met the study criteria. 31.21% of the patients were discarded for transplantation on a first visit. The final cohort of potential transplant candidates who completed the pre-transplant study was 119 (69%) and 47 finally received a lung transplant (39.5%). The most frequent COPD phenotype evaluated for lung transplantation was the exacerbator (59%), followed by the non-exacerbator (38%) and the Asthma COPD Overlap [ACO] (3%). 59.8% of the exacerbator-phenotype patients assessed did not complete the pre-transplant study. Exacerbator-phenotype patients have a lower post-transplant survival (1115.1 days [standard deviation-DE-587]) vs. ACO: 1432 days [DE 507.5] and Non-exacerbators: 1317.8 days [DE 544.7] p = 0.16), although this difference has not been statistically significant. Conclusions. The most frequent COPD phenotype assessed for lung transplantation is the exacerbator, although more than half of these patients fail to complete the pre-transplant study.[Resumen] Introducción. Se desconoce la prevalencia de los fenotipos de EPOC que son remitidos para valorar el trasplante pulmonar, así como si un fenotipo específico tiene influencia en la evolución postrasplante en aquellos pacientes que lo reciben. Materiales y métodos. Estudio observacional ambispectivo, sin intervención. El objetivo principal fue conocer la prevalencia de los diferentes fenotipos de EPOC de los pacientes que fueron remitidos para valorar un trasplante de pulmón. Los objetivos secundarios fueron comparar sus características clínicas para realizar un análisis de la supervivencia postrasplante o de las complicaciones de acuerdo con el fenotipo. Resultados. Se valoró a 502 pacientes para la realización de un trasplante de pulmón, de los cuales 173 cumplían los criterios del estudio. El 31,21% de los pacientes fue descartado para el trasplante en la primera visita. La cohorte final de candidatos potenciales a trasplante que completaron el estudio pretrasplante fue de 119 pacientes (69%) y, finalmente, 47 recibieron el trasplante de pulmón (39,5%). El fenotipo de EPOC que se evaluó con mayor frecuencia para el trasplante de pulmón fue el agudizador (59%), seguido del no agudizador (38%) y el mixto EPOC-asma (3%). El 59,8% de los pacientes con fenotipo agudizador valorados no completó el estudio pretrasplante. Los pacientes con fenotipo agudizador presentan una supervivencia postrasplante más baja (1.115,1 días; desviación estándar [DE]: 587) frente a los mixto EPOC-asma (1.432 días; DE: 507,5) y los no agudizadores (1.317,8 días; DE: 544,7; p = 0,16), aunque esta diferencia no fue estadísticamente significativa. Conclusiones. El fenotipo más frecuentemente estudiado para el trasplante de pulmón es el agudizador, aunque más de la mitad de estos pacientes no completa el estudio pretrasplante

    International audienceThis paper presents a set of experimental results concerning the sliding mode control of an electro-pneumatic system. Two discrete-time control strategies are considered for the implementation of the discontinuous part of the sliding mode controller: explicit and implicit discretizations. While the explicit implementation is known to generate numerical chattering [6], [7], [12], [13], the implicit one is expected to significantly reduce chattering while keeping the accuracy. The experimental results reported in this work remarkably confirm that the implicit discrete-time sliding mode supersedes the explicit ones, with several important features: chattering in the control input is almost eliminated (while the explicit and saturated controllers behave like high-frequency bang-bang inputs), the input magnitude depends only on the perturbation size and is largely independent of the controller gain and sampling time

    Myeloid-Derived Suppressor Cells (MDSCs), immunosuppressive cells that promote tumor growth, represent an attractive target in cancer immunotherapy. However, the clinical success of this strategy is limited by the lack of efficient drug delivery vehicles targeting this cell compartment. The objective of this work was to develop a delivery carrier, multilayer polymer nanocapsules, with the capacity to co-encapsulate two types of immunomodulatory drugs, a chemokine and an RNAi sequence, aimed at reverting MDSC-mediated immunosuppression. The chemokine CCL2, intended to attract monocyte-macrophage MDSCs, was encapsulated within the L2 inverse micellar aqueous domains of the lipid core of these nanocapsules. On the other hand, two different RNAi sequences that modulate the CCAAT/enhancer-binding protein beta (C/EBPβ) pathway, shC/EBPβ and miR 142-3p, were successfully associated to their polymer shell. These RNAi sequences were covered by subsequent layers of polyarginine and hyaluronic acid, thereby creating multi-layered assemblies that protected them and facilitated their targeted delivery. The in vitro studies performed in primary MDSCs cultures showed the capacity of miR 142-3p-loaded nanocapsules to reduce the highly immunosuppressive monocyte- macrophage subset. Additionally, the encapsulation of CCL2 within the nanocapsules induced a potent monocyte-macrophage chemoattraction that could be used to direct the therapy to these cell subsets. Finally, in vitro and in vivo studies showed the capacity of shC/EBPβ-loaded nanocapsules to downregulate C/EBPβ levels in MDSCs and to reduce monocyte differentiation into tumor-associated macrophages in an MCA-203 fibrosarcoma mice model. In conclusion, the multilayer polymer nanocapsules described here are efficient vehicles for the co-delivery of proteins and RNA, and are potential candidates as nanomedicines for the modulation of MDSCs.This work was supported by LYMPHOTARG (ERA-NET EuroNanoMed ProgramISCIII, ref PS09/02670) and NICHE projects (ERA-NET EuroNanoMed II framework by ISCIII through CIBER- BBN), which received funding from the European Union's Seventh Framework Programme.

    Resveratrol and its 2-methoxy derivative pterostilbene are two phenolic compounds that occur in foodstuffs and feature hepato-protective effects. This study is devoted to analysing and comparing the metabolic effects of pterostilbene and resveratrol on gut microbiota composition in rats displaying NAFLD induced by a diet rich in saturated fat and fructose. The associations among changes induced by both phenolic compounds in liver status and those induced in gut microbiota composition were also analysed. For this purpose, fifty Wistar rats were distributed in five experimental groups: a group of animals fed a standard diet (CC group) and four additional groups fed a high-fat high-fructose diet alone (HFHF group) or supplemented with 15 or 30 mg/kg bw/d of pterostilbene (PT15 and PT30 groups, respectively) or 30 mg/kg bw/d of resveratrol (RSV30 group). The dramatic changes induced by high-fat high-fructose feeding in the gut microbiota were poorly ameliorated by pterostilbene or resveratrol. These results suggest that the specific changes in microbiota composition induced by pterostilbene (increased abundances of Akkermansia and Erysipelatoclostridium, and lowered abundance of Clostridum sensu stricto 1) may not entirely explain the putative preventive effects on steatohepatitis.This research was funded by Ministerio de Economía y Competitividad-Fondo Europeo de Desarrollo Regional (grant number AGL-2015-65719-R MINECO/FEDER, UE), Instituto de Salud Carlos III CIBERobn (grant number CB12/03/30007); University of the Basque Country (grant number GIU 18/173)

    Canine adenovirus type 1 (CAdV-1) in free-ranging European brown bear (Ursus arctos arctos): A threat for Cantabrian population?

    Get PDF
    [EN] Canine adenovirus type 1 (CAdV-1) is responsible for infectious canine hepatitis. The disease has been described in captive American black bear (Ursus americanus) and European brown bear (Ursus arctos arctos), with just one recently reported case in a cub of a free-ranging brown bear (Ursus arctos horribilis) from Alaska. The aim of this work is to summarize findings related to presence and associated mortality of CAdV-1 in 21 free-ranging Cantabrian brown bears (Ursus arctos arctos) submitted to necropsy in Asturias and Castilla y León (northwestern Spain) from 1998 to 2018. On the basis of the anatomopathological findings and laboratory results three free-ranging brown bears died due to infectious canine hepatitis, which is to our knowledge the first description of death due to this disease in free-ranging bears in Europe. Gross lesions consisted of petechial haemorrhages and congestion in different internal organs, haemorrhagic fluid in internal cavities, friable and yellowish liver and thickening of gall bladder. Microscopic lesions were observed mainly in liver, kidney and brain and consisted of multifocal necrosis of cells with presence of basophilic intranuclear inclusions. Immunohistochemical (IHC) and real-time polymerase chain reaction (qPCR) techniques were used to assess the presence of CAdV-1 in paraffin-embedded liver samples. Viral antigens were detected by IHC labelling within hepatocytes and Küppfer cells in the three animals. The presence of viral DNA was confirmed by qPCR in one of them. In order to evaluate the circulation of CAdV-1 in brown bears, a retrospective study was performed using both IHC and qPCR techniques in 11 and 12 additional brown bears, respectively. An extra brown bear was found positive by IHC. This study shows that CAdV-1 surveillance of brown bears and sympatric carnivores should be considered as major concern for the monitoring the population evolution throughout time in this endangered species.SIAuthors thank colleagues from SERIDA (A.

    Objective Cultural backgrounds and values have a decisive impact on the phenomenon of the wish to die (WTD), and examination of this in Mediterranean countries is in its early stages. The objectives of this study were to establish the prevalence of WTD and to characterise this phenomenon in our cultural context. Methods A cross-sectional study with consecutive advanced inpatients was conducted. Data about WTD (Assessing Frequency & Extent of Desire to Die (AFFED) interview) and anxiety and depression (Edmonton Symptom Assessment System-revised (ESAS-r)) were collected through two face-to-face clinical encounters. Data were analysed with descriptive statistics, χ2 and analysis of variance. Results 201 patients participated and 165 (82%) completed both interviews. Prevalence of WTD was 18% (36/201) in the first interview and 16% (26/165) in the second interview (p=0.25). After the first interview, no changes in depression (p=0.60) or anxiety (p=0.90) were detected. The AFFED shows different experiences within WTD: 11% of patients reported a sporadic experience, while 7% described a persistent experience. Thinking about hastening death (HD) appeared in 8 (22%) out of 36 patients with WTD: 5 (14%) out of 36 patients considered this hypothetically but would never take action, while 3 (8%) out of 36 patients had a more structured idea about HD. In this study, no relation was detected between HD and frequency of the appearance of WTD (p=0.12). Conclusions One in five patients had WTD. Our findings suggest the existence of different experiences within the same phenomenon, defined according to frequency of appearance and intention to hasten death. A linguistically grounded model is proposed, differentiating the experiences of the ‘wish’ or ‘desire’ to die, with or without HD ideation

    <p>Abstract</p> <p>Background</p> <p>The prevalence of overweight and obesity (OW/OB) among adolescents worldwide has increased since the 60 s. Spain has reached one of the highest OW/OB prevalence rates among adolescents from European countries. The aim of this methodological paper is to describe the design and evaluation in the EVASYON study (Development, implementation and evaluation of the efficacy of a therapeutic programme for adolescents with OW/OB: integral education on nutrition and physical activity).</p> <p>Methods/Design</p> <p>The EVASYON was planned by a multidisciplinary team to treat OW/OB in Spanish adolescents. The EVASYON is a multi-centre study conducted in 5 hospitals in 5 Spanish cities (Granada, Madrid, Pamplona, Santander and Zaragoza) and two hundred and four OW/OB Spanish adolescents were recruited for this intervention. The treatment was implemented for approximately one-year follow-up. The adolescents were treated in groups of a maximum of 10 subjects; each group had 20 visits during the treatment period in two phases: intensive during the first 2 months (1<sup>st </sup>to 9<sup>th </sup>visits), and extensive during the last 11 months (10<sup>th </sup>to 20<sup>th </sup>visits). In order to assess the efficacy of the treatment, 8 dimensions were measured: diet; physical activity and fitness; eating behaviour; body composition; haematological profile; metabolic profile; minerals and vitamins; immuno-inflammatory markers. Moreover, genetic polymorphisms were also determined.</p> <p>Discussion</p> <p>The treatment programme developed in the EVASYON study was designed as a national pilot study to be implemented as an effective treatment for adolescents with OW/OB into the Spanish Health Care Service.</p

    Long-term adoption of reduced tillage and green manure improves soil physicochemical properties and increases the abundance of beneficial bacteria in a Mediterranean rainfed almond orchard

    Soil health and function is one of the most important components for sustainable management of woody orchards. Intensive use of machinery and tillage creates heavy pressure on agroecosystems by altering the soil physicochemical and biological characteristics. In this study we aimed to assess the changes in soil physicochemical properties and the soil bacterial community structure, as well as the main drivers involved in shifts in the microbial community following 10 years implementing reduced tillage and reduced tillage plus green manure in a rainfed Mediterranean almond orchard. The treatments were: i) conventional tillage (CT); ii) reduced tillage (RT); and iii) reduced tillage and diversification with Avena sativa and Vicia sativa (RTD). After ten years, the results showed that the different managements had no significant effect on almond yields. RTD significantly increased total organic carbon (TOC), with an average content of 19.5 g kg−1 compared to 17.1 g kg−1 in CT. RTD also contributed to an increase in the fraction of soil macro-aggregates. Both RT and RTD significantly increased soil total nitrogen (NT) and particulate organic carbon (POC). However, other physical and chemical variables such as exchangeable Ca, Mg and K, bioavailable Fe, Cu, Zn and Mn, cation exchange capacity, bulk density, wilting point and field capacity were not significantly affected by the management. The bacterial community significantly changed with management: RTD showed a higher relative abundance of the family Solirubrobacteraceae and the genera Streptomyces and Solirubrobacter. The bacterial community structure was explained by changes in TOC, POC, pH, and NT values. Thus, a combination of reduced tillage and green manure could represent an appropriate sustainable management for rainfed almond orchards in very fragile environmental conditions, due to an increase in soil organic matter, total nitrogen, and the higher presence of beneficial bacteria related to soil productivity.This work was supported by the European Commission Horizon 2020 project Diverfarming [grant agreement 728003].
