Estado actual y tendencias de la investigación en el campo de la construcción
Muoz Martialay, R.
Informes de la Construccion , 1979,
Abstract: An analysis is presented here of the possible causes of the current crisis afflicting research work in Spain, particularly in the field of construction and some suggestions are advanced which, in the author's opinion, must be taken into account when the time comes to state a scientific research policy in such field. Se presenta a continuación un análisis de las posibles causas que han determinado la situación de crisis en que se encuentra actualmente la investigación en Espa a, especialmente en el campo de la construcción, y se exponen algunas ideas orientativas que deberían tenerse en cuenta, a juicio del autor, a la hora de plantear una política científica en dicho campo.
Síndrome de apnea hipopnea del sue?o e ictus
Muoz,R.; Ramos,C.;
Anales del Sistema Sanitario de Navarra , 2007, DOI: 10.4321/S1137-66272007000200008
Abstract: for many years attention has been drawn to the frequent association between sleep apnea-hypopnea syndrome and stroke. numerous and very different epidemiological studies are available that point to a possible causal relation. in a parallel way, there has been an increase over these years in the knowledge of the different intermediate physiopathological mechanisms by which apnea could theoretically favour the appearance of cerebral ischemia. an increase in arterial pressure, the appearance of arrhythmias, hemodynamic changes in cerebral circulation and a prothrombotic state are outstanding amongst these. likewise, it was also proved that treatment with cpap was beneficial for normalising some of these alterations. nonetheless, it is only recently that, thanks to the appearance of different prospective studies, it has been irrefutably proved that sahs is a risk factor that increases the possibility of suffering an stroke, independently of the presence of other classical risk factors. while awaiting new intervention studies that confirm whether treatment with cpap reduces this risk, it is important to include in the anamnesis of patients who have suffered an stroke or a transitory ischemic accident the search for data that would lead us to think of sahs and to send these patients for evaluation by the respiratory unit when necessary.
Síndrome de apnea hipopnea del sue o e ictus Sleep apnea-hypopnea syndrome and stroke
R. Muoz,C. Ramos
Anales del Sistema Sanitario de Navarra , 2007,
Abstract: Desde hace a os se ha llamado la atención sobre la frecuente asociación entre el Síndrome de apnea hipopnea del Sue o (SAHS) y el ictus. Disponemos de múltiples y muy diversos estudios epidemiológicos que se alan una posible relación causal. De forma paralela, a lo largo de estos a os se ha incrementado el conocimiento de distintos mecanismos fisiopatológicos intermedios por los que teóricamente la apnea podría favorecer la aparición de isquemia cerebral. Entre estos destacaban un incremento de la presión arterial, la aparición de arritmias, cambios hemodinámicos de la circulación cerebral y un estado protrombótico. Asimismo, también se ha comprobado cómo el tratamiento con CPAP era beneficioso para normalizar algunas de estas alteraciones. Sin embargo, no ha sido hasta muy recientemente cuando, gracias a la aparición de diversos estudios prospectivos, se ha demostrado de forma fehaciente que el SAHS es un factor de riesgo que incrementa la posibilidad de padecer un ictus isquémico, de forma independiente a la presencia de otros factores de riesgo clásicos. En espera de nuevos estudios de intervención que confirmen si el tratamiento con CPAP reduce este riesgo, es importante incluir en la anamnesis de pacientes que hayan sufrido un ictus o un accidente isquémico transitorio la búsqueda de datos que nos hagan pensar en un SAHS y remitir a estos pacientes a valoración por el Servicio de Neumología en caso necesario.

Leishmania panamensis transmission in the domestic environment: the results of a prospective epidemiological survey in Santander, Colombia
Muoz,Gerardo; Davies,Clive R;
Biomédica , 2006,
Abstract: introduction. domestic transmission now appears to be the principal route of leishmania panamensis infection in deforested regions characterized by the replacement of primary forest by permanent plantations, i,e coffee or cacao crops. this paper presents the results of the disease patterns in a representative population of the opón focus, in santander, colombia. objective. the principal aims were: 1) to measure the incidence rate in a representative population of the opón focus; 2) to identify demographic risk factors for infection; 3) to estimate the proportion of infections which cause disease; 4) to estimate the protection against disease from acquired immunity; 5) to estimate the frequency of reactivations, and 6) to estimate the risk of mucosal leishmaniasis. material and methods. a 19 month prospective survey of leishmaniasis caused by leishmania panamensis was carried out amongst 1380 people in a cacao growing region of santander department, colombia. the population was diagnosed clinically and by the montenegro skin test (at two time points). results: the incidence rate was 0.19 infections/person-year, with 31% of infections apparently subclinical. the risk of acquiring cutaneous leishmaniasis decreased with age even in the absence of apparent previous infections. protective immunity followed both clinical and subclinical infections, persisting for at least 10 years after a primary lesion. mucocutaneous leishmaniasis was detected in 12% of the population with cutaneous lesions, of which 77% had mild symptoms, and 23% perforated nasal septa. the risk of mucosal leishmaniasis was greatest for males, and for people whose primary cutaneous lesion was on the head. conclusion. the average age of infection in opón, 7.7 years (1/l), and the absence of gender as a risk factor is highly indicative of intradomiciliary or peridomiciliary transmission.
USO DE PLANTAS EN RITUALES FUNERARIOS DEL PERíODO FORMATIVO EN ARICA1
Muoz Ovalle,Iván R.;
Chungará (Arica) , 2001, DOI: 10.4067/S0717-73562001000100025
Abstract: the archaeological excavations of cemeteries from the formative period (500 bc to 200 ad) give evidence regarding the utilization, by the alto ramírez populations, of a great variety of plants, in the conformation of levels, which are superimposed with layers of earth. this particular form of burial of the dead -the construction of mounds-constitutes an important indicator for understanding the cultural process of said era, where other aspects were consolidating the process of formation of farming village

Anular o acortar los primeros pelda os de la Escalera Analgésica de la OMS To annul or to shorten the first steps of the WHO Analgesic Leader
A. Rubio,E. Muoz,R. Sierra
Revista de la Sociedad Espa?ola del Dolor , 2008,
Abstract: Objetivo: Consideramos la posibilidad de anular o acortar el segundo pelda o de la escalera analgésica de la OMS, con el propósito de controlar el dolor crónico de nuestros pacientes en el menor tiempo posible. Material y métodos: Presentamos un estudio sobre 74 pacientes, divididos en tres grupos, para valorar si existen diferencias entre ellos. Un primer grupo pasó a tratarse con fentanilo TTS sin tratamiento previo con opioides débiles, los otros dos se trataron anteriormente con tramadol a dosis distintas. Un grupo a dosis previas de tramadol comprendidas entre 1 y 3 mg/Kg y otro grupo con dosis comprendidas entre 3.5 y 6 mg/Kg. Resultados: Los resultados han sido similares, clínica y estadísticamente, en cuanto a efectos secundarios, control del dolor y abandonos. Conclusiones: Concluimos que es posible acortar el tiempo necesario para controlar el dolor crónico en pacientes con patologías severas y que se presuponga necesitarán la prescripción de opioides mayores y que se puede anular el primer escalón de la OMS y también acortar el segundo. Objective: This study was designed to evalúate the possibility of either shorten or annul the first and second level of the WHO-analgesic ladder; in order to achieve pain control in patientes suffering from OA within the shortest period of time. Material and Methods: - First group pain was not adequately controlled by non-opioid analgesic and afterwards treated with TD-Fentanyl. - The second group was treated with TDF after not being adequately controlled by weak opoids, with a dose that ranged between 1 mg up to 3 mg/kg. - The third group was treated with TDF after a dose of weak opioids (tramadol) which ranged between 3,5 mg up to 6 mg/kg. Results: Results related to pain control, adverse effects and therapy discontinuing, were statistically and clinically similar among the three groups. Conclusion: It is possible to shorten the period of time necessary to achieve pain control in patients who suffer from chronic pain related to OA by shorting or avoiding the second or first level of the WHO-anlgesic ladder.

Educaci?3n M??dica Superior , 2007,
Abstract: En este artículo se planteó que considerando las características didácticas del aprendizaje basado en problemas, se requiere de un cambio de mentalidad de los docentes universitarios para apropiarse de una nueva racionalidad evaluativa, la que debe estar constituida por elementos teóricos, conceptuales y prácticos, a fin de evaluar el conocimiento, las habilidades y las actitudes de los estudiantes, además de promover en ellos su participación en el proceso evaluativo. In present paper it is expound that considering didactic features of based on-learning problem, it is necessary a mentality change of university professors to achieve a new evaluation rationality, which must to include theoretical, conceptual, and practical elements, to assess knowledge, abilities, and attitudes of students, in addition to their involvement in assessing process.
