Cicatrices hipertróficas y queloideas: unificación de criterios e implementación de conocimientos
2019
El proceso de cicatrización del organismo tiende a la reparación del tejido dañado, pero dicho proceso puede alterarse por distintas circunstancias. Por ello se pueden producir una cicatrización: normal, excesiva o insuficiente. El objetivo de este estudio es elaborar una infografía, para ayudar al profesional sanitario a realizar un diagnóstico diferencial entre las cicatrices hipertróficas y queloideas, y exponer las diferentes opciones de prevención y tratamientos más habituales. Material y método: Se realizó una revisión bibliográfica sobre el tema. Resultados: Se han seleccionado un total de 26 artículos, que nos han permitido realizar una infografía, estructurada en tres apartados: 1)…
Improving childhood obesity treatment using new technologies: the ETIOBE System
2011
Childhood obesity is an increasing public health problem in western culture. Sedentary lifestyles and an “obesogenic environment” are the main influences on children leading to an increase in obesity. The objective of this paper is to describe an e-health platform for the treatment and prevention of childhood obesity called ETIOBE. This e-health platform is an e-therapy system for the treatment of obesity, aimed at improving treatment adherence and promoting the mechanisms of self-control in patients, to obtain weight loss maintenance and to prevent relapse by establishing healthy lifestyle habits. ETIOBE is composed of three different applications, the Clinician Support System (CSS), the H…
Back Pain: Pathophysiology, Diagnosis, and Treatment
2023
Although back pain is one of the most common medical conditions [1], with a reported general population prevalence close to 50% along their lifetime in a long-term British survey [2], it does not attract the interest it should from the general population [3], political powers [4,5] and scientific community [6]. Patients keep coming to our offices for a surgical solution to their back pain, hoping that a miraculous operation will solve all their problems [3,7]. Yet, the surgical procedure sometimes does not solve the problem, and it can be the cause of a new nightmare in one third of patients [8,9]. A Japanese study found that 95% of their patients had persistent back pain after surgery at t…
Intimate partner violence in older women in Spain: prevalence, health consequences, and service utilization.
2013
The purpose of this study is to estimate the prevalence of lifetime intimate partner violence (IPV) in older women and to analyze its effect on women"s health and Healthcare Services utilization. Women aged 55 years and over (1,676) randomly sampled from Primary Healthcare Services around Spain were included. Lifetime IPV prevalence, types, and duration were calculated. Descriptive and multivariate procedures using logistic and multiple lineal regression models were used. Of the women studied, 29.4% experienced IPV with an average duration of 21 years. Regardless of the type of IPV experienced, abused women showed significantly poorer health and higher healthcare services utilization compar…
Hepatitis C Crónica y usuarios con un historial de inyección de drogas en España: evaluación de la población, retos para un tratamiento efectivo.
2017
La hepatitis C cronica (HCC) es una enfermedad de desigualdad que afecta desproporcionadamente a las personas desatendidas por la salud publica. Personas con antecedentes de uso de opioides o uso de drogas por via parenteral (UDVP) se enfrentan a desigualdad y estigma. Un historia previa de inyeccion de drogas es un comportamiento que incrementa el riesgo de contraer el VHC. Hay una gran incidencia de HCC entre las personas se inyectan drogas. Hay mas de 300,000 personas en Espana que actualmente se inyectan drogas o tienen antecedentes. Hay 150,000 personas en Espana con un historial trastorno de uso de opioides y la mayoria son UDVP o ex UDVP. Aproximadamente 80,000 personas usan los serv…
A Semi-Industrial Anmbr Plant for Urban Wastewater Treatment at Ambient Temperature: Analysis of the Filtration Process, Energy Balance and Quantific…
2022
A semi-industrial scale AnMBR urban wastewater treatment plant was operated for 580 days at ambient temperature (ranging from 10-30 ○C) to assess its long-term filtration performance, energy balance and GHG emissions. The applied 20ºC-standardized transmembrane flux (J20) was varied between 15 and 25 LMH and the specific gas demand per m2 of membrane (SGDm) was modified between 0.10 to 0.40 Nm3·m-2·h-1 (corresponding to a specific gas demand per permeate volume (SGDP) between 10 to 20 Nm3·m-3). The filtration strategy allowed successful long-term operations without any chemical cleaning requirements and little fouling for 233 days. The plant operated as a net energy producer for more than 5…
Optimising an outdoor membrane photobioreactor for tertiary sewage treatment
2019
[EN] The operation of an outdoor membrane photobioreactor plant which treated the effluent of an anaerobic membrane bioreactor was optimised. Biomass retention times of 4.5, 6, and 9 days were tested. At a biomass retention time of 4.5 days, maximum nitrogen recovery rate:light irradiance ratios, photosynthetic efficiencies and carbon biofixations of 51.7¿±¿14.3¿mg¿N·mol¿1, 4.4¿±¿1.6% and 0.50¿±¿0.05¿kg CO2·m3influent, respectively, were attained. Minimum membrane fouling rates were achieved when operating at the shortest biomass retention time because of the lower solid concentration and the negligible amount of cyanobacteria and protozoa. Hydraulic retention times of 3.5, 2, and 1.5 days …
Improving membrane photobioreactor performance by reducing light path: operating conditions and key performance indicators
2020
[EN] Microalgae cultivation has been receiving increasing interest in wastewater remediation due to their ability to assimilate nutrients present in wastewater streams. In this respect, cultivating microalgae in membrane photobioreactors (MPBRs) allows decoupling the solid retention time (SRT) from the hydraulic retention time (HRT), which enables to increase the nutrient load to the photobioreactors (PBRs) while avoiding the wash out of the microalgae biomass. The reduction of the PBR light path from 25 to 10 cm increased the nitrogen and phosphorus recovery rates, microalgae biomass productivity and photosynthetic efficiency by 150, 103, 194 and 67%, respectively.The areal biomass product…
Production of microalgal external organic matter in a Chlorella-dominated culture: influence of temperature and stress factors
2020
[EN] Although microalgae are recognised to release external organic matter (EOM), little is known about this phenomenon in microalgae cultivation systems, especially on a large scale. A study on the effect of microalgae-stressing factors such as temperature, nutrient limitation and ammonium oxidising bacteria (AOB) competition in EOM production by microalgae was carried out. The results showed non-statistically significant differences in EOM production at constant temperatures of 25, 30 and 35 degrees C. However, when the temperature was raised from 25 to 35 degrees C for 4 h a day, polysaccharide production increased significantly, indicating microalgae stress. Nutrient limitation also see…
Utilización de sistemas informáticos para el diseño de estaciones de tratamiento de aguas residuales
1994
Los sistemas informáticos para el diseño de Estaciones de Tratamiento de Aguas Residuales (ETAR) resultan de gran utilidad para la toma de decisiones relacionadas con la gestión de la calidad del agua en el medio natural. En este artículo se presenta el sistema DATAR, desarrollado para el diseño completo y riguroso de una ETAR que cumpla las especificaciones impuestas al vertido. Para ello se han desarrollado modelos matemáticos que describen los procesos que tienen lugar en los distintos elementos de tratamiento considerando los parámetros de calidad demanda biológica de oxígeno a los 5 días (DBO5), demanda química de oxígeno (DQO), sólidos suspendidos (SS), nitrógeno Kjeldhal (NKT) y fósf…
