Data base of manuscript "Clinical and Psychosocial Predictors of Physical Activity in Systemic Lupus Erythematosus: a Multicentre Cross-Sectional Study", Background/Objectives: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterised by musculoskeletal manifestations such as myopathies, arthritis, and arthralgia. Physical activity may improve patients’ perceived quality of life and over-all wellbeing. The objective was to assess physical activity levels in patients with SLE and to identify the main clinical, sociodemographic, and anthropometric variables influencing these levels. Methods: A multicentre cross-sectional study was conducted including 64 patients with SLE. Clinical variables were extracted from medical records, while pa-tient-reported outcomes were collected at the survey. The dependent variable was physical activity, assessed with the International Physical Activity Questionnaire. Independent variables included fatigue (FAS), quality of life (SF-36), sleep (PSQI), depression (BDI-II), anxiety (HARS), age, disease factors (activity, duration, damage), sex, smoking, and comorbidities. Results: Significant associations were observed between physical activity levels and smoking status (χ²=11.88; p=0.003), sleep quality (χ²=6.81; p=0.03), and anxiety (χ²=18.39; p=0.001). In multivariable analyses, poor sleep (PSQI>5) (OR=14.40; 95% CI: 2.50–82.99), higher anxiety (HARS; per point OR=1.12; 95% CI: 1.05–1.20), and higher SF-36 Physical Component Summary (PCS) scores (per point OR=1.29; 95% CI: 1.15–1.45) were associated with being in a higher physical activity category. Given the counterintui-tive direction for sleep and the limited model fit, these findings should be interpreted cau-tiously. Conclusions: In patients with SLE, physical activity was associated with smoking, sleep disturbances, and anxiety. Strongest associations were observed for sleep quality, anxiety, and physical health, although results require validation in larger, diverse cohorts, particularly regarding sleep–activity links.

El proyecto SALMAFood aborda uno de los grandes retos contemporáneos a los que se enfrenta la alimentación en las sociedades actuales: la transformación hacia sistemas alimentarios más saludables, sostenibles y justos. A través de un enfoque interdisciplinar y multiactor, el equipo de investigación ha analizado el malestar ciudadano con la alimentación, los desafíos del sistema agroalimentario español y las propuestas de mejora impulsadas desde distintos sectores sociales. Los resultados de esta investigación permiten confirmar donde se encuentra los focos del malestar de la ciudadanía con el sistema alimentario y también se ha visibilizado el bienestar que produce la preparación y el consumo alimentario. Esta dualidad ha sido posible al plantear un avance metodológico en el análisis del sistema alimentario, en el que se ha trabajado sobre los eslabones tradicionales (producción, industria, distribución y consumo) pero se ha añadido como elementos del sistema la preparación de los alimentos y la comensalidad, incorporando el hogar como espacio de análisis sobre la alimentación., Base de datos de la encuesta realizada a la población española sobre las percepciones y valoraciones sobre el sistema alimentario., Ministerio de Ciencia innovación y universidades.

The Asymmetric Double Cantilever Beam (ADCB) is a common test configuration used to produce mixed mode I/II in composite materials. It consists of two sublaminates with different thicknesses or elastic properties, a situation that usually occurs in bimaterial adhesive joints. During this test, the sample undergoes rotation. In this work, the influence of this rotation on the calculation of the energy release rate (ERR) in modes I and II was studied using the Finite Element Method (FEM). Several models with different degrees of asymmetry (different thickness ratio and/or elastic modulus ratio) and different applied displacements were prepared to obtain different levels of rotation during the test. As is known, the concept of modes I and II refers to the components of the energy release rate calculated in the direction perpendicular and tangential to the delamination plane, respectively. If the model experiences significant rotation during the application of the load, this non-linearity must be considered in the calculation of the mode partition I/II. In this work, appreciable differences were observed in the values of modes I and II, depending on their calculation in a global system or a local system that rotates with the sample. When performing crack growth calculations, the difference between critical loads can be in the order of 4%, while the difference between mode I and mode II results can reach 4% and 14%, respectively, for an applied displacement of only 5 mm. Currently, this correction is not usually implemented in Finite Element calculation codes or in analytical developments. The purpose of this article is to draw attention to this aspect when the rotation of the specimen is not negligible., This research received no external funding.

Monitoring metabolites through non-invasive methods is revolutionizing clinical analysis, with decentralized and faster tests. Sweat, a readily available biological fluid that requires non-invasive and simple procedures, is emerging as a valuable source of key biomarkers, such as glucose and ethanol. In this work, an enzymatic nanobiosensor for simultaneous determination of glucose and ethanol in sweat samples has been developed. The electrochemical platform consists of two working electrodes onto which Pd nanoclusters (PdNCs) with catalytic activity for the oxygen reduction reaction were deposited. Additionally, each WE was modified either with glucose oxidase (GOx) or alcohol oxidase (AOx). Thus, the simultaneous quantification of both analytes, glucose and ethanol, was performed thanks to the localized decrease in the concentration of dissolved O2 produced at each WE by the oxidase enzymes. This resulted in a reduction of the current density measured by cyclic voltammetry. Sweat samples were collected using a polyamide membrane that permits extremely rapid analysis without the need for any external solution or sample pretreatment, making the method user-friendly and well-suited for self-analysis. The results revealed the capability of the nanobiosensor for determining the increase in the level of both analytes in sweat after the consumption of alcoholic beverages and energy drinks., This work was financially supported through projects PID2023-148375OB-I00 and PID2022- 137319OB-C21 funded by MCIN/AEI/10.13039/501100011033/ FEDER, UE, and the Government of the Principality of Asturias through the Sekuens Agency, and EU through the FEDER Program (IDE/2024/000694).
