Chronic Obstructive Pulmonary Disease and Incidence of Hip Fracture: A Nested Case-Control Study in the EpiChron Cohort
Purpose: To determine whether chronic obstructive pulmonary disease (COPD) is a risk factor for hip fracture and identify other factors associated with hip fracture.
Patients and Methods: Observational nested case-control study was conducted in Aragon, Spain in 2010. We included COPD patients aged >40 years, in the EpiChron cohort. Each COPD patient was matched for age, sex, and number of comorbidities with a control subject without COPD. Patients with an existing diagnosis of osteoporosis and those with hip fracture before 2011 were excluded. We collected baseline demographic, comorbidity, and pharmacological treatment data. During a 5-year follow-up period, we recorded the incidence of hip fracture. A logistic regression model was constructed to identify factors associated with hip fracture.
Results: The study population consisted of 26, 517 COPD patients and the same number of controls (median [interquartile range] age, 74 [17] years; women, 24.7%). Smoking and heart failure were more frequent in COPD patients, and obesity, hypertension, diabetes, dyslipidemia, stroke, arthritis, and visual or hearing impairment were less frequent (all p<0.001). Consumption of benzodiazepines (p=0.037), bronchodilators (p<0.001), and corticosteroids (p<0.001) was higher in the COPD group, while that of beta-blockers and thiazides was lower (both p<0.001). During follow-up, 898 (1.7%) patients experienced hip fracture, with no differences observed between COPD and control patients. Multivariate analysis revealed that independent of COPD status, age, female sex, chronic liver disease, heart failure, and benzodiazepine use were independently associated with a higher risk of hip fracture, and obesity with a lower risk. In COPD patients, use of inhaled anticholinergics was independently associated with hip fracture (OR, 1.390; 95% CI 1.134-1.702; p=0.001).
Conclusion: COPD is not a risk factor for a hip fracture within 5 years. The association between the use of inhaled anticholinergics and risk of hip fracture warrants further study
"Click & collect" para una rápida adaptación de la docencia práctica presencial a online en grados universitarios de Ciencias de la Salud
La obligada adaptación del proceso enseñanza/aprendizaje a entornos no presenciales, debido a la expansión del virus SARS-COV-2, ha motivado el diseño y ejecución de herramientas de aprendizaje basadas en TICs, que integren, además de los contenidos indispensables para la adquisición de competencias profesionales, un entorno atractivo para el aprendizaje autónomo de los alumnos. Mediante un paquete informático de implementación rápida ("click & collect") en plataformas virtuales de diferentes universidades, adaptado al nivel medio de conocimientos informáticos del profesorado en Ciencias de la Salud, se han diseñado unas clases prácticas de la asignatura Farmacognosia y Fitoterapia correspondiente a los Grados de Farmacia y Farmacia y Nutricion Humana y Dietética de la UCM y las Universidades CEU San Pablo y CEU Cardenal Herrera. Se han incluido presentaciones ppsx interactivas y micro-vídeos de prácticas reales, incluyendo aciertos y fallos más comunes.

Uso de compuestos nutracéuticos en nuevas formulaciones de piensos acuícolas
Trabajo presentado en las X Jornadas de Acuicultura en el Litoral Suratlántico: Nuevos retos y perspectivas para la sostenibilidad de la acuicultura, celebrado entre el 22 y 23 de noviembre de 2023 en Huelva.[EN] Different strategies have been followed to improve the aquaculture of main European farmed fish, such as genetic selection, refinements in culture conditions or enhanced feed formulation and management. However,
more knowledge is required to exploit fish phenotypic plasticity to obtain those that better match aquaculture or market conditions. The overall objective of this mini-review is to identify the latest productive traits recently
performed, mainly in commercial carnivorous species, and underlying biological processes that would be susceptible to improve the competitivity of aquaculture sector through nutritional issues. Thus, this work is
framed within the concepts of Circular Economy and Blue Growth, where it is intended to point out the use of natural compounds extracted from seaweeds, microalgae and by-products of the industry for their inclusion in
aquafeeds, allowing a more efficient use of more sustainable vegetable protein sources, and also to evaluate if these nutraceutical compounds counteract detrimental effects observed by nutritional interventions or
environmentally challenged.[ES] La producción acuícola ha seguido diferentes estrategias para su optimización a lo largo de las últimas décadas, como el desarrollo de la selección genética, la mejora de las condiciones de cultivo, o el avance en la
formulación y gestión de los piensos. Sin embargo, se requiere más conocimiento para explotar la plasticidad fenotípica de los peces para obtener aquellos que se ajusten mejor a las condiciones de la acuicultura o del
mercado. El objetivo general de esta mini-revisión es identificar los últimos avances realizados recientemente, principalmente en especies carnívoras comerciales, y los procesos biológicos subyacentes que serían
susceptibles de mejorar la competitividad del sector acuícola a través de intervenciones nutricionales. Así, este trabajo se enmarca dentro de los conceptos de Economía Circular y Crecimiento Azul, donde se pretende señalar el uso de compuestos naturales extraídos de algas, microalgas y subproductos de la industria para su inclusión en alimentos acuícolas, permitiendo un uso más eficiente de fuentes de proteínas vegetales más sostenibles, y también evaluar si estos compuestos nutracéuticos son capaces de contrarrestar los efectos perjudiciales observados por las formulaciones inadecuadas o desafiados por factores ambientales estresantes.This work was supported by the Projects “FEDER-UCA18-107182”, “FisioBream-II Call for Young Researchers CEI⋅MAR 2019”, “ALGAE4FISH-CEI·MAR Empresa 2018”, “VALINVA-CEI·MAR Empresa 2019”, “SeriBlue-CEI·MAR Empresa 2020”, and co-financed by the spin-off LifeBioencapsulation S.L.

Colorectal adenomas contain multiple somatic mutations that do not coincide with synchronous adenocarcinoma specimens
We have performed a comparative ultrasequencing study of multiple colorectal lesions obtained simultaneously from four patients. Our data show that benign lesions (adenomatous or hyperplastic polyps) contain a high mutational load. Additionally multiple synchronous colorectal lesions show non overlapping mutational signatures highlighting the degree of heterogeneity between multiple specimens in the same patient. Observations in these cases imply that considering not only the number of mutations but an effective oncogenic combination of mutations can determine the malignant progression of colorectal lesions
PRIMAGE project : predictive in silico multiscale analytics to support childhood cancer personalised evaluation empowered by imaging biomarkers
PRIMAGE is one of the largest and more ambitious research projects dealing with medical imaging, artificial intelligence and cancer treatment in children. It is a 4-year European Commission-financed project that has 16 European partners in the consortium, including the European Society for Paediatric Oncology, two imaging biobanks, and three prominent European paediatric oncology units. The project is constructed as an observational in silico study involving high-quality anonymised datasets (imaging, clinical, molecular, and genetics) for the training and validation of machine learning and multiscale algorithms. The open cloud-based platform will offer precise clinical assistance for phenotyping (diagnosis), treatment allocation (prediction), and patient endpoints (prognosis), based on the use of imaging biomarkers, tumour growth simulation, advanced visualisation of confidence scores, and machine-learning approaches. The decision support prototype will be constructed and validated on two paediatric cancers: neuroblastoma and diffuse intrinsic pontine glioma. External validation will be performed on data recruited from independent collaborative centres. Final results will be available for the scientific community at the end of the project, and ready for translation to other malignant solid tumours

Deterioro y Conservación de Materiales Geológicos del Patrimonio
La actividad investigadora desarrollada por el Instituto de Geociencias en el campo del deterioro y conservación de materiales geológicos parten siempre de la caracterización petrológica y mineralógica de los materiales utilizados en el patrimonio. Se utilizan técnicas petrográficas, geoquímicas y petrofísicas, con apoyo de técnicas mineralógicas y cristalográficas para establecer su estado de conservación y definir las causas de alteración. Los avances del conocimiento se dirigen a establecer la interrelación entre las propiedades de los materiales pétreos, tanto de superficie como internas, con el medio ambiente. Desde la petrología y la mineralogía experimental se abordan problemas referentes a la mejora de productos de conservación, en base a sus características petrofísicas y a su comportamiento en ambientes agresivos. Con estas investigaciones se pueden determinar las técnicas de conservación más eficaces e idóneas para cada tipo de material y ambientes a los que se encuentran sometidos los materiales. Por lo tanto, la investigación se inicia con la caracterización, continúa estableciendo las causas de deterioro y, por último, ofrece soluciones para mejorar la calidad de los materiales e incrementar su durabilidad, desarrollando técnicas de conservación que han generado patentes
Early B-cell Factor gene association with multiple sclerosis in the Spanish population
BACKGROUND: The etiology of multiple sclerosis (MS) is at present not fully elucidated, although it is considered to result from the interaction of environmental and genetic susceptibility factors. In this work we aimed at testing the Early B-cell Factor (EBF1) gene as a functional and positional candidate risk factor for this neurological disease. Axonal damage is a hallmark for multiple sclerosis clinical disability and EBF plays an evolutionarily conserved role in the expression of proteins essential for axonal pathfinding. Failure of B-cell differentiation was found in EBF-deficient mice and involvement of B-lymphocytes in MS has been suggested from their presence in cerebrospinal fluid and lesions of patients. METHODS: The role of the EBF1 gene in multiple sclerosis susceptibility was analyzed by performing a case-control study with 356 multiple sclerosis patients and 540 ethnically matched controls comparing the EBF1 polymorphism rs1368297 and the microsatellite D5S2038. RESULTS: Significant association of an EBF1-intronic polymorphism (rs1368297, A vs. T: p = 0.02; OR = 1.26 and AA vs. [TA+TT]: p = 0.02; OR = 1.39) was discovered. This association was even stronger after stratification for the well-established risk factor of multiple sclerosis in the Major Histocompatibility Complex, DRB1*1501 (AA vs. [TA+TT]: p = 0.005; OR = 1.78). A trend for association in the case-control study of another EBF1 marker, the allele 5 of the very informative microsatellite D5S2038, was corroborated by Transmission Disequilibrium Test of 53 trios (p = 0.03). CONCLUSION: Our data support EBF1 gene association with MS pathogenesis in the Spanish white population. Two genetic markers within the EBF1 gene have been found associated with this neurological disease, indicative either of their causative role or that of some other polymorphism in linkage disequilibrium with them
