    Carprofen (CP), a non-steroidal anti-inflammatory drug (NSAID), is profusely used in veterinary medicine for its analgesic and anti-inflammatory activity. Some undesirable effects are associated with its systemic administration. Alternative local routes are especially useful to facilitate its administration in animals. The main aim of this paper is to validate the suitability of ex vivo permeation experiments of CP with porcine mucous membranes (buccal, sublingual and vaginal) and ophthalmic tissues (cornea, sclera and conjunctiva) intended to be representative of naïve in vivo conditions. Chromatographic analysis of CP in membrane-permeated samples and drug-retained have been validated following standard bioanalytical guidelines. Then, recovery levels of drugs in tissue samples were assessed with aqueous phosphate buffered saline (PBS) buffer to preserve the histological integrity. Finally, as a proof of concept, a series of CP permeation tests in vertical Franz diffusion cells has been performed to evaluate permeation flux and permeability constants in all tissues, followed by a histological study for critical evaluation. Furthermore, synthetic tissue retention-like samples were prepared to verify the value of this experimental study. Results show linear relationships with good determination coefficient (R2 > 0.998 and R2 > 0.999) in the range of 0.78 to 6.25 mg/mL and 3.125 mg/mL to 100 mg/mL, respectively. Low limits of quantification around 0.40 µg/mL were allowed to follow permeation levels until a minimum of 0.40% of the locally-applied dose. This method showed a good accuracy and precision with values lower than 2%. After the recovery technique, reproducible values below 30% were achieved in all tissues, suggesting it is a non-damaging method with low efficiency that requires the use of further solvents to enhance the extraction percentages. After permeation and histology tests, no relevant peak interferences were detected, and no cell or tissue damage was found in any tissue. In conclusion, results demonstrate the suitability of this test to quantify the distribution of CP with good histological tolerability

    The transition from secondary education to university education has become a critical moment for the lifestyle of young people, especially for the practice of physical activity. Therefore, the main objective of the present study was to assess the levels of physical activity in university students, by correlating the results of the IPAQ-SF and the different physical fitness variables (Eurofit). The sample consisted of 194 students of the Primary Education Degree, with a mean age of 21.37 ± 2.66 years. The main results obtained reflect the direct relationship between the practice of physical activity in general, and vigorous physical activity in particular, and optimal physical fitness of university students, linked above all to the strength component. As for the comparison between pre-pandemic (18/19) and post-pandemic (21/22) university students, the increase in physical activity after the pandemic did not show substantial differences in the physical fitness components. In conclusion, these results should lead us to reflect on the influence of an active lifestyle on physical fitness, which has an impact on overall health status and quality of life.El tránsito de la educación secundaria a la enseñanza universitaria se ha convertido en un momento crítico para el estilo de vida de los jóvenes, especialmente para la práctica de actividad física. Por ello, el principal objetivo del presente estudio fue valorar los niveles de actividad física en universitarios, mediante la correlación entre los resultados del IPAQ-SF y las distintas variables de condición física (Eurofit). La muestra estuvo conformada por 194 estudiantes del Grado de Educación Primaria, con una edad media de 21,37 ± 2,66 años. Los principales resultados obtenidos reflejan la relación directa entre la práctica de actividad física en general, y la actividad física vigorosa en particular y una óptima aptitud física de los estudiantes universitarios, vinculada sobre todo con el componente fuerza. En cuanto a la comparación entre los universitarios del curso prepandémico (18/19) y el curso pospandémico (21/22), el aumento de la actividad física tras la pandemia no reportó diferencias sustanciales en los componentes de la condición física. A modo de conclusión, estos resultados deben conducirnos a una reflexión sobre la influencia de un estilo de vida activo en la aptitud física, la cual tiene repercusión en el estado de salud general y la calidad de vida

    Las relaciones geométricas y cinemáticas entre las unidades de basamento de los Pirineos Suroccidentales, específicamente entre la terminación de la Zona Axial y el afloramiento de los Macizos Vascos, son desconocidas y potencialmente muy complejas (Oliva-Urcia, 2018). La gravimetría se ha aplicado con éxito en otras regiones pirenaicas para resolver la geometría de las unidades de cobertera y basamento debido al contraste de densidad existente en las rocas involucradas. Con el objetivo de resolver dichas relaciones y sus implicaciones en la comprensión 4D de esta parte de la cadena, hemos llevado a cabo un exhaustivo programa de adquisición de datos gravimétricos (2018-2020) entre los valles de Salazar (al oeste) y del Aragón Subordán (hacia el este) en el marco del proyecto 3DGeoEU (GeoERA-H2020). Más de 1500 nuevas estaciones (varias de ellas en alta montaña) junto con > 1700 puntos de la base de datos SITOPO, ¿ 1200 de campañas mineras, y > 500 de anteriores proyectos del IGME hacen un total de > 5000 estaciones gravimétricas armonizadas. Además, se han recopilado > 500 datos de densidad de bases de datos o muestreados en el campo. En este trabajo presentaremos los mapas de anomalías Bouguer y de anomalía residual obtenidos, junto con una revisión de las principales estructuras cartográficas en la zona

    Objective: To know those predictive factors of hyperglycemia that could guide us the design of a parenteral nutrition and it could avoid later complications associated with it. Methods: A prospective observational study was designed; adult hospitalized patients who received total parenteral nutrition at least 48 hours were included. Nutritional and pharmacotherapeutic follow-up were performed according to usual practice. Variables collected included demographic, clinical, analytical and nutrition and pharmacotherapy. Results: Fifty-eight patients were included, with 28 patients (48.3%) with glucose restriction. This intervention was statistically associated with elevated glycemia prior to parenteral nutrition (OR: 1.38, 95% CI 1.11-1.73, p = 0.004) and BMI (OR: 1.29, 95% CI 1.05-1.58, p = 0.014), with more frequent intervention was in patients with BMI > 25 (overweight and obese) (OR: 10.00; 95% CI 1.15-86.95, p = 0.037). Conclusions: Pre-parenteral glycemic values, diabetes and BMI values > 25 are predictors of hyperglycemia, so a early intervention to prevent and correct hyperglycemia may improve clinical outcomes in patients with parenteral nutritio
