ABSTRACT

Realizar un análisis métrico de la producción científica de los institutos del Sistema Nacional de Salud de la República de Cuba durante el período 2000-2004 en las revistas de la corriente principal. Se realizó una búsqueda en el Web of Science. La estrategia de búsqueda se basó en el empleo de la palabra Cuba en el campo Author Address. Se analizaron los indicadores de producción, impacto y colaboración internacional. La colaboración y las temáticas de investigación se presentaron mediante grafos basados en el análisis de redes sociales. Los institutos de salud totalizaron 295 trabajos, que representaron el 33,20 por ciento de la producción del sector sanitario y el 8,9 por ciento de todos los documentos nacionales registrados en la base de datos estudiada, con una tendencia al aumento. El Instituto de Medicina Tropical “Pedro Kourí” y el Instituto de Neurología y Neurocirugía participaron en el 38,0 por ciento y 24,1 por cientodel total artículos. Se observó una correspondencia entre el porcentaje de colaboraciones internacionales y los niveles de citación de los artículos. La colaboración internacional se manifestó en el 43,4 por ciento de los artículos vinculados con un total de 61 países de los 5 continentes. Los índices de citación de las colaboraciones internacionales tuvieron generalmente valores superiores. Los institutos nacionales de salud poseen un gran peso en la investigación y la producción científica del sector sanitario cubano. Las líneas de investigación predominantes se relacionan con los problemas prioritarios de salud del país.


To make a metric analysis of the scientific production of the institutes of the National System of Health of the Republic of Cuba during the period 2000-2004 in the main current magazines. METHODS: A search in the Web of Science was carried out. The search strategy was based on the use of the word Cuba in the Author Address field. An analysis of the production, impact and international collaboration indicators was made. The collaboration and the research topics were presented by means of graphs based on the analysis of social networks. The health institutes totalized 295 papers, accounting for 33.20 per cent of the production of the health sector and the 8.90 per cent of all the national documents registered in the studied database, with a tendency towards increase. "Pedro Kourí" Institute of Tropical Medicine and the Institute of Neurology and Neurosurgery participated in the 38.0 per cent and 24.1 per cent of the total of articles. A correspondence was observed between the percentage of international collaborations and the article citation levels. The international collaboration was expressed in 43.4 per cent of the articles linked with a total of 61 countries of the 5 continents. The citation indexes of the international collaborations had generally greater values. The national health institutes play an important role in the research and scientific production of the Cuban health sector. The predominant research lines are related to the prioritized health problems of the country.

ABSTRACT

Se realizó un studio cienciométrico del Reporte Técnico de Vigilancia, publicación de la Unidad de Análisis y Tendencias en Salud del Ministerio de Salud Pública de Cuba. Se analizó la producción científica en el período 1996-2006 desde la perspectiva de género, para identificar la presencia femenina en la vigilancia en salud y aportar la base informacional que contribuya a la toma de decisiones en torno a las políticas editoriales y científicas en este contexto disciplinario e institucional. Se mostraron las relaciones de colaboración científica entre autores, instituciones y especialidades. Se observó el predominio de las mujeres en la autoría, presentes en más del 90 por ciento del total de artículos. No obstante, se evidenció la tendencia al aumento de la colaboración entre ambos sexos, y el predominio de las mujeres como autoras principales en casi un 70 por ciento de los artículos...


A scientometric study of the Reporte Técnico de Vigilancia, a journal of the Health and Analysis Trends Unit from the Cuban Ministry of Public Health, was carried out. The scientific production in the period 1996-2006 was analyzed based on gender perspective, in order to identify the presence of women in the Health Surveillance context for supporting decision making processes on publishing and scientific policies. The collaboration networks between authors, institutions and specialties were visualized. Women were predominant in the authorship. They participated in the 90 per cent the articles. However, an increase of the collaboration between both sexes was evidenced. Women were the first author in the 70 per cent of the articles...

ABSTRACT

Estudou-se o efeito da superalimentação no desenvolvimento do esqueleto de 14 cães da raça Dogue Alemão, utilizando dieta hipercalórica (ração super-premium) associada ao método de alimentação à vontade. Os animais foram distribuídos em dois tratamentos, sendo a ração fornecida à vontade ou restrita. O consumo de alimento foi registrado diariamente e realizaram-se, mensalmente, radiografias do cotovelo e, bimestralmente, do ombro, do quadril e do carpo, visando acompanhar alterações do esqueleto, especificamente quanto ao aparecimento da osteocondrose do ombro e da metáfise distal da ulna, da osteodistrofia hipertrófica e da displasia coxofemoral (DCF). Ao final do experimento, seis cães do grupo que recebeu alimentação à vontade apresentaram-se gordos (87,7 por cento) e um animal obeso (14,3 por cento). Do grupo de alimentação restrita, três filhotes mostraram condição corporal ideal (42,8 por cento), e quatro apresentaram-se magros (57,2 por cento). O exame radiológico revelou alterações compatíveis com o diagnóstico de DCF nos dois grupos; nos alimentados à vontade, a prevalência foi de 51,1 por cento e nos restritos, de 28,6 por cento. A osteocondrose na metáfise distal da ulna, conhecida como retenção do núcleo cartilaginoso, foi observada apenas nos cães alimentados à vontade (57,1 por cento). A superalimentação provocada pelo método de alimentação à vontade, associada com dieta de alta palatabilidade e alta densidade energética em filhotes da raça Dogue Alemão, induziu ao aparecimento de osteocondrose na metáfise distal da ulna e de displasia coxofemoral.


The effects of overfeeding on growing Great Dane puppies were examined by ad libitum feeding of a hypercaloric diet (super premium ration). Fourteen puppies from six litters were divided into two groups, with representation from each litter in each group. The dogs in the overfed group were provided ad libitum access to the diet from 8 AM to 6 PM daily, while the restricted group received the same feed but in amounts recommended by the manufacturer at 7 AM, 12:30 PM and 5 PM. Daily intake was individually recorded. To monitor skeletal changes due to osteochondrosis, hypertrophic osteodystrophy and hip dysplasia, elbow radiographs were taken monthly and shoulder, pelvis and corpus radiographs were taken bi-monthly. Weekly feed consumption and weight gain were greater in ad libitum than in restricted puppies (P<0.01). At the end of the experiment, 85.7 percent of the ad libitum group was over weight and 14.3 percent was obese, whereas 57.2 percent of restricted puppies were slim and 42.8 percent had ideal body weight. None of the dogs had hypertrophic osteodystrophy. Radiographic examination showed alterations compatible with hip dysplasia in both groups, but such observations were more frequent and more severe in the ad libitum group. Osteochondrosis of metaphisis distal ulna, known by the retention of cartiloginous nucleus, was observed only in the ad libitum group, at a rate of 57.1 percent. The thickness of the cortical and diameter of the ulna were greater (P<0.01) in ad libitum dogs than in those fed a restricted amount of the same diet. In summary, overfeeding caused by ad libitum access to a highly palatable and high energy food caused osteochondrosis and hip dysplasia in Great Dane puppies.
