Prognostic Factors in Staged Bilateral Total Knee Arthroplasty—A Retrospective Case Series Analysis
2023
Background: Bilateral osteoarthritis of the knee is an indication for a bilateral total knee replacement (TKR) procedure. The goal of our study was to assess the sizes of the implants used during the first and second stages of TKR procedures in order to compare their size and identify the prognostic factors for the second procedure. Methods: We evaluated 44 patients who underwent staged bilateral TKR procedures. We assess the following prognostic factors from the first and second surgery: duration of anesthesia, femoral component size, tibial component size, duration of hospital stay, tibial polyethylene insert size, and the number of complications. Results: All assessed prognostic factors …
THE USE OF MBR SYSTEMS FOR THE TREATMENT OF REAL SHIPBOARD SLOPS: ANALYSIS OF BIOLOGICAL PERFORMANCE AND BIOMASS BIOKINETIC ACTIVITY
2016
In order to prevent hydrocarbon discharge at sea from ships, the International Maritime Organization (IMO) enacted the MARPOL 73/78 convention in which any oil and oil residue discharged in wastewater streams must contain less than 5 ppm hydrocarbons. Effective treatment of this petroleum-contaminated water is essential prior to its release into the environment, in order to prevent pollution problem for marine ecosystems as well as for human health. The present paper reports the first results of a field gathering campaign aimed at gaining insight about the treatment of real shipboard slops with a MBR pilot plant, in terms of pilot performance and biomass biokinetic activity. The achieved re…
Inmigracion y abuso de sustancias. Una aproximación a la realidad española
2008
Resumen tomado de la publicación Se realiza una aproximación al estudio de las características del abuso de sustancias entre la población inmigrante en España. Aunque no se puede establecer una relación unívoca entre emigración y abuso de sustancias, hay factores sociales, culturales e incluso biológicos, que aumentan el riesgo en dicha población, tal como confirma el incremento del indicador de demandas de tratamiento en el último año en la Comunidad Valenciana. Se repasan aspectos epidemiológicos como número de demandas de tratamiento y tipo de sustancias consumidas según la procedencia. En la etiopatogenia de las adicciones en la inmigración destacan sobre todo factores sociales y psicol…
Extracellular Vesicle microRNAs Contribute to the Osteogenic Inhibition of Mesenchymal Stem Cells in Multiple Myeloma
2020
Osteolytic bone disease is the major complication associated with the progression of multiple myeloma (MM). Recently, extracellular vesicles (EVs) have emerged as mediators of MM-associated bone disease by inhibiting the osteogenic differentiation of human mesenchymal stem cells (hMSCs). Here, we investigated a correlation between the EV-mediated osteogenic inhibition and MM vesicle content, focusing on miRNAs. By the use of a MicroRNA Card, we identified a pool of miRNAs, highly expressed in EVs, from MM cell line (MM1.S EVs), expression of which was confirmed in EVs from bone marrow (BM) plasma of patients affected by smoldering myeloma (SMM) and MM. Notably,we found that miR-129-5p, whic…

Estudio de la expresión de marcadores de transición epitelio-mesenquimal y de célula madre cancerosa en el melanoma cutáneo, y su asociación con la p…
2015
La mayoría de los estudios epidemiológicos muestran un aumento en la incidencia de melanoma en las últimas décadas, sobre todo a expensas de un aumento en la incidencia de melanomas delgados. La búsqueda de nuevos marcadores pronósticos y predictivos incluye el estudio de el fenómeno de transición epitelio-mesenquimal (EMT) que consiste en un proceso dinámico por el que las células adquieren progresivamente un fenotipo mesenquimal, con pérdida de las uniones célula-célula, modificaciones en el citoesqueleto y adquisición de marcadores como cadherina-N, osteonectina/SPARC, osteopontina, fibronectina, Twist y Snail. Por otro lado, en el modelo de tumorigénesis de la célula madre cancerosa (CM…
Energy efficient model for biogas production in farm scale
2011
Energy efficient solutions for six farm biogas production was found by calculating mass and energy balance in different scenarios. Raw materials in biogas production were cow manure and grass silage that were produced in these farms. There were calculated mass and energy balances on average for one year biogas prouduction that consisted of grass silage production, raw material transportation and biogas production in the biogas plant. In addition, direct greenhouse gases from biogas production were estimated. The direct mass and energy flows were calculated. It turned out that one input energy unit can produce 5.0 to 5.5 energy units as heat and electricity. Biogas reactor consumed heat from…
Prevalencia de la hipertensión arterial y factores asociados en población adulta de la Comunitat Valenciana
2014
La hipertensión es el principal factor de riesgo en términos de mortalidad atribuible y el principal factor de riesgo cardiovascular modificable. Los objetivos del estudio han sido: estimar la prevalencia de hipertensión arterial en población adulta de la Comunitat Valenciana, describir el grado de conocimiento, tratamiento y control de la hipertensión y la fuerza de asociación entre determinados factores y la presencia de hipertensión arterial. El punto de partida ha sido una submuestra de 413 hombres y 415 mujeres de edades comprendidas entre los 16 y los 90 años del estudio transversal de base poblacional (encuesta de nutrición) realizado en la Comunitat Valenciana entre 2010 y 2011. Com…
