Abstract: background: given that there are different ways of setting out clinical test results, this study is aimed at ascertaining whether the way in which these results are set out has any bearing on the intention to prescribed on the part of primary care physicians. methods: randomized, multi-center cross-study. following a random sampling of eight primary care teams in the province of ourense (spain), two groups of family physicians (na=45 and nb=51) were surveyed by means of a questionnaire on which the data from five published clinical tests (three on heart disease prevention, one on cognitive benefit in a dementia syndrome and another on preventing fractures among the elderly) was shown. one of the groups was shown the data as a relative lowering of the risk, and the other as the necessary number of individuals to be treated. age, gender and years of practice were also asked. following a three-week blanking period, the intervention was reversed. the intention of prescribing was gathered on a 0-10 likert scale. the c2, simple student t were used, or the pearson test for paired data and correlation, according to whether an error a de 0.05 were to be achieved. results: test a: ci95% (-1.55~0.17); b: ci95% (-2.75~-1.20); c: ci95% (-0.16~1.65); d: ci95% (-0.30~1.44); e: ci95% (-1.22~0.35). no difference with regard to gender, age or professional experience were found. regarding the overall effect, with the exception of one of the tests presented, no significant differences were found concerning the intention of prescribing the drugs involved in terms of the way in which the data was set out. conclusions: the way in which clinical test data is set out has no bearing in itself on the ntention to prescribe medications.

Abstract: Fundamento: Conocer la opinión de los médicos de atención primaria de Ourense (Espa a) con respecto a algunos aspectos de su prescripción como el conocimiento del precio de los fármacos, la prescripción inducida percibida, la relación con la industria farmacéutica y la opinión del médico sobre posibles medidas reductoras del gasto farmacéutico. Métodos: En este estudio transversal descriptivo, se entrevistó mediante un cuestionario postal, previamente probado, a todos los médicos de atención primaria (MAP) de la provincia de Ourense (243). En él se recogían características demográficas de los facultativos, influencia del coste en la prescripción, estimación del precio de 15 fármacos de uso habitual y la opinión sobre diversos aspectos relacionados con la prescripción inducida, la industria farmacéutica y diversas estrategias para contener el gasto en farmacia. Para el análisis de los resultados se utilizaron pruebas de ji2, t de Student y análisis de la varianza, así como el coeficiente de correlación de Spearman según cumpliera con un error alfa de 0,05. Resultados. El nivel de participación de los encuestados fue del 42,8 % (104). La duración media diaria de la visita de los delegados farmacéuticos fue de 13,6 minutos, siendo las novedades el punto de mayor interés. Casi un 27 % admitía participar en ensayos clínicos patrocinados por la industria. El 23 % consideraba el precio una prioridad al prescribir. La prescripción inducida suponía el 39,7 % del total. Los facultativos eligieron mayoritariamente el copago para reducir el gasto farmacéutico. En la estimación del precio el porcentaje de error global fue del 45,7 %, subestimando los más caros y sobrestimando los más baratos. Conclusiones. Existe un desconocimiento importante del precio de los fármacos entre los MAP. La mayor parte de los médicos no consideran que el precio del fármaco deba ser una prioridad al prescribir. Hay un porcentaje elevado de prescripción inducida percibida. Respecto al gasto farmacéutico, la mayor parte de los MAP considera las medidas económicas, en concreto el copago, como las más efectivas para su contención.

Abstract: background: to evaluate the degree to which the metabolic check-up objectives among type ii diabetes patients were met in rural primary care by comparing them to the values recommended by the american diabetes association (ada) and the diabetes in primary care study group (gedaps). methods: descriptive cross-sectional study. a sample size was calculated based on the glycosolated hemoglobin (hba1c) test in 119 individuals. a total of 253 patients with type ii diabetes followed up for at least two years at their healthcare facility took part. the patients in question were selected at random from among 17 medical lists at 11 rural healthcare facilities in the province of ourense (spain). demographic variables, cardiovascular risk factors, pharmacological treatment, self-analyses, eye fundus, tactile sensitivity, hba1c, lipid profile, blood pressure and body mass index data were taken from the patients′ clinical records. results: a total of 44.3% of those in the sample had undergone an hba1c test within the immediately prior six-month period, showing a value of under seven percent (7%). a total of 21.2% had a blood pressure of under 130/80, and 19.8% a ldl cholesterol level of under 100 mg/dl. a total of 40.7% of those patients with a ldl cholesterol level over 100 were not undergoing any hypolipemiant treatment. a total of 20.4% of the patients showing high blood pressure readings were not undergoing any blood pressure lowering treatment. on the basis of these three factors, a total of 2.5% met the check-up objectives. thirty-six percent (36%) were antiaggregated with aas. conclusions: a major deficit is revealed both in the frequency of the check-ups conducted by the healthcare professionals as well as the number of interventions performed for achieving the proposed objectives, showing results far below what is recommended in the clinical practice guidelines.
Natural and laser-induced cavitation in corn stems: On the mechanisms of acoustic emissions
E. Fernández,R. J. Fernández,Gabriel Mario Bilmes
Papers in Physics , 2012,
Abstract: Water in plant xylem is often superheated, and therefore in a meta-stable state. Under certain conditions, it may suddenly turn from the liquid to the vapor state. This cavitation process produces acoustic emissions. We report the measurement of ultrasonic acoustic emissions (UAE) produced by natural and induced cavitation in corn stems. We induced cavitation and UAE in vivo, in well controlled and reproducible experiments, by irradiating the bare stem of the plants with a continuous-wave laser beam. By tracing the source of UAE, we were able to detect absorption and frequency filtering of the UAE propagating through the stem. This technique allows the unique possibility of studying localized embolism of plant conduits, and thus to test hypotheses on the hydraulic architecture of plants. Based on our results, we postulate that the source of UAE is a transient "cavity oscillation"' triggered by the disruptive effect of cavitation inception.
Protoglobicephala mexicana, a new genus and species of Pliocene fossil dolphin (Cetacea; Odontoceti; Delphinidae) from the Gulf of California, Mexico
Aguirre-Fernández, Gabriel;Barnes, Lawrence G.;Aranda-Manteca, Francisco J.;Fernández-Rivera, Jorge R.;
Boletín de la Sociedad Geológica Mexicana , 2009,
Abstract: the delphinidae is the most diverse living family of odontocete cetaceans and includes modern oceanic dolphins and their fossil relatives. in contrast, the world-wide fossil record of this family is sparse when compared to that of several other cetacean groups, and relatively few extinct delphinids have been formally named. most of the known fossil delphinidae are of pliocene age, and most of these are from europe. we describe a new genus and new species of extinct delphinidae, protoglobicephala mexicana, based on a cranium of pliocene age, between approximately 2 and 3 million years old, from isla san jose in the gulf of california, baja california sur, mexico. this species shares with recent species of globicephala wide exposures of the premaxillae on the dorsal surface of the rostrum and rugose areas on the distal ends of the premaxillae. like other globicephalinae members, it is a relatively large animal and has a wide cranium, short and broad rostrum, and relatively few teeth that are of relatively large size. it also shares some similarities with the generalized delphinine delphinid tursiops. these similarities and the geochronologically relatively young occurrence of this new species reinforce previous notions that the present taxonomic diversity of the family delphinidae is the result of rapid evolutionary diversification since miocene time, or within approximately the past five million years. the ability of living species of delphinidae in different genera, and in different nominal subfamilies, to mate and to produce viable hybrid offspring, offers additional support for the idea of rapid and recent evolutionary diversification of this family.

Abstract: Introducción: Con el objetivo de promover la interrelación entre jóvenes y mayores institucionalizados se inició, en la isla de Lanzarote, el proyecto Aprendamos Juntos. Metodología: Participaron alumnos de primaria y mayores de una residencia con un nivel de deterioro moderado. Se realizaron dos sesiones de trabajo en el centro de ense anza y otras dos en la residencia de ancianos. Resultados: El nivel de satisfacción de los participantes fue elevado. Se apreció en los ni os un cambio de actitud respecto a la figura del mayor. Se constató en los ancianos un aumento de la motivación y de la actividad habitual. Se incrementó la satisfacción laboral de los profesionales. Conclusiones: Las acciones emprendidas no actúan como mera actividad lúdica, sino que tienen una función terapéutica. Son significativos los cambios de actitud que se producen en los ni os con respecto al mayor. El abordaje interdisciplinar permite a los profesionales alcanzar más fácilmente los objetivos terapéuticos. Destacamos los beneficios obtenidos a pesar del reducido coste del proyecto. Introduction: In order to promote the interaction between children and elderly, the project Aprendamos Juntos (Let's Learn Together) was carried out in Lanzarote (Canary Islands). Methodology: Students from a local school and the residents of a nursing home, with moderate physical impairment, participated in the project. Two sessions took place in the school and two in the nursing home. Results: There was a high level of satisfaction. It was noticed that the children had a change of attitude with regard to their respect of the elderly. We verified that there was an increase in the motivation and in the daily activity of the latter. The professionals also experienced increased work satisfaction. Conclusions: The activities that have been undertaken work not only as playful activity, but also have a therapeutic function. The changes in the attitude of the children with respect to the elderly are very significant. The interdisciplinary vision allowed the professionals involved to achieve their therapeutic objectives with ease. We point out the numerous benefits which have been attained in spite of the very low cost of the project.
Entrevistas en auto-confrontación: un método en clínica de la actividad
Gabriel Fernández,Yves Clot
Laboreal , 2007,
Abstract: We present a co-analysis of work methodology and a correlative method that we call a crossed self-confrontation. It involves distinguishing between work done and "real" work. Our aim is to identify the activity′s potential developments, in order to eventually transform their course. The method is composed of three phases. The first involves co-design of the work environment. It is followed by a second phase of video recordings of what the operators do and what they say about it in simple and crossed self-confrontation. The third phase involves the collective′s appropriation of the professional dialogues produced in the self-confrontation. The results obtained with this type of analysis, inseparable from an activity clinic, allows us to approach health as the subject′s power to act on his or her self and environment.
