Caracterización perinatal del recién nacido macrosómico
Molina Hernández,Orlando Rafael; Monteagudo Ruiz,Consuelo Leonor;
Revista Cubana de Obstetricia y Ginecolog?-a , 2010,
Abstract: the macrosomia newborn is a heterogeneous group and of vital significance, its birth is a risky problem for the perinatology specialists. a case-control study was conducted to characterize the macrosomia newborn in the "mariana grajales" teaching provincial hospital of santa clara in 2007, to relate the mother and neonatal variables selected for study and control groups, as well as to compare the morbidity of macrosomia newborns and of those with a normal weight. the study group included all the live births neonates weighing 4000g or more and the control group included the live births following macrosomia, excluding those with low-birth weight and twins. information was gathered from a designed method to that end including the mother and neonatal variables and data were tabulated and showed in tables to express the results. it is emphasized that the 11 % of all live births had macrosomia with significant variables like age similar or greater than 35 years, multiparity, macrosomia and gestational diabetes. also, there was an statistic association including the labor at 42 weeks or more of pregnancy, body mass index (bmi) higher than 26 at pregnancy onset and the excessive weight gain (more than 15 kg). frequent neonatal morbidity: pulmonary edema, hypoglycemia, hypocalcaemia, metabolic acidosis, worsening physiological icterus, polyglobulin ant birth traumata without affecting the mortality in the institution. it is necessary the prenatal and perinatal care to limit the unfavorable results in the mother-child duo.

Abstract: El recién nacido macrosómico representa un grupo heterogéneo y de vital relevancia, el nacimiento de ellos constituye un problema de riesgo para los perinatólogos. Se realizó un estudio de casos y controles, con los objetivos de caracterizar al recién nacido macrosómico en el Hospital Ginecoobstétrico Provincial Docente "Mariana Grajales" de Santa Clara en el a o 2007, relacionar las variables maternas y neonatales seleccionadas para los grupos estudio y control, así como comparar la morbilidad de los recién nacidos macrosómicos con los neonatos normopesos. El grupo estudio incluyó todos los neonatos nacidos vivos con 4000 g o más de peso y el grupo control los nacidos vivos siguientes al macrosómico, se excluyeron los bajo peso al nacer y los gemelares. La información se obtuvo de un instrumento confeccionado al efecto que incluyó variables maternas y neonatales y los datos fueron tabulados y expuestos en tablas para expresar los resultados. Se destaca que el 11 % de todos los nacidos vivos fueron macrosómicos, resultaron significativas variables como la edad igual o mayor de 35 a os, la multiparidad, antecedentes de macrosomía y la diabetes gestacional. También se asociaron estadísticamente: el parto a las 42 sem o más de gestación, índice de masa corporal superior a 26 al inicio del embarazo y la ganancia excesiva de peso (más de 15 kg). Morbilidad neonatal frecuente: edema pulmonar, hipoglicemia, hipocalcemia, acidosis metabólica, íctero fisiológico agravado, la poliglobulia y los traumas al nacer, no afectando la mortalidad del centro. Se recomienda atención prenatal y perinatal de calidad para limitar resultados desfavorables en el binomio madre-hijo.

Revista Cubana de Cirugía , 2010,
Abstract: INTRODUCCIóN. A partir del 2007 comenzó a popularizarse la cirugía endoscópica transumbilical, probablemente como consecuencia de los retos aún no resueltos que la cirugía endoscópica transluminal a través de orificios naturales ha debido enfrentar para su aplicación en la práctica clínica. Hasta la fecha se han descrito técnicas de cirugía endoscópica transumbilical con endoscopia flexible, con trocares multicanales, con varios trocares en una sola incisión, así como diferentes sistemas de retracción, tales como la retracción con suturas (técnicas de marionetas) y la retracción magnética. El objetivo de esta investigación fue evaluar en un modelo porcino la factibilidad de una nueva técnica de colecistectomía endoscópica transumbilical. MéTODOS. Se realizó un estudio prospectivo longitudinal en 6 cerdos con peso entre 22 y 26 kg. Se practicó la colecistectomía endoscópica transumbilical desde un puerto, con un solo canal de trabajo y con un nuevo sistema de retracción vesicular (TORCAM). La eutanasia de los animales se realizó de manera inmediata y fueron evaluadas las variables: factibilidad, calidad de exposición, efectos adversos del sistema de retracción, tiempo quirúrgico y examen macroscópico posoperatorio de la zona quirúrgica. RESULTADOS. La calidad de la retracción y exposición de la vesícula fue considerada óptima en todos los casos, lo que permitió la realización de la técnica quirúrgica en el 100 % de la muestra. No se reportaron complicaciones ni efectos adversos asociados al sistema de retracción vesicular. El tiempo quirúrgico promedio fue de 46 min. CONCLUSIONES. La colecistectomía endoscópica transumbilical propuesta es una nueva técnica que demostró ser factible en el modelo animal. INTRODUCTION. From 2007 transumbilical endoscopic surgery to become popular probably as a consequence of the not yet solved challenges that transluminal endoscopic surgery through natural orifices has faced for its application in the clinical practice. Up to date have been described the techniques of Transumbilical endoscopic surgery with flexible endoscopy, with multi-channels, with some trocars in a only incision, as well as different retraction systems like that of the suture retraction (marionette techniques) and the magnetic retraction. The aim of present research was to assess in a pig model the feasibility of a new Transumbilical endoscopic cholecystectomy technique. METHODS. A longitudinal and prospective study was conducted in 6 pigs weighing between 22 and 26 kg. The above mentioned technique was applied from a portal, with an only work channel a

Abstract: in order to analyze trends in land use change in the lechuguilla-ohuira-navachiste watershed (sinaloa), as well as their impact on runoff patterns, a geographic information system (gis) was integrated with land use/cover thematic maps, soil cartography and rainfall time-series. land use/cover thematic maps, with accuracies > 85 %, were produced by supervised classification of landsat satellite imagery (1973, 1986, and 2000). agriculture was the main land use during the study period, covering between 34 % and 45 % of the basin area. at the landscape level, changes amounted to 33 % from 1973 to 1986, and 27 % from 1986 to 2000, mainly associated with shrub vegetation and agriculture classes, which changed at mean annual rates of 2.1 % and 0.6 %, respectively, from 1973 to 2000. to evaluate the impact of landscape changes on the watershed runoff, the curve number model was used, obtaining mean annual runoff volume estimates of 198 x 106 m3 in 1973, 302 x 106 m3 in 1986 and 197 x 106 m3 in 2000. those volumes correspond to runoff coefficients of 16 %, 20 %, and 23 %, respectively. the results indicate that changes in runoff volumes in the study area depend more on the variation of precipitation rates than those observed in land uses and cover changes, because of the high proportion of fine-textured soils, with little infiltration rates and runoff potential resistant to changes in land use.

DINáMICA NUTRICIONAL EN CINCO PARRONES DE DIFERENTE PRODUCTIVIDAD DEL VALLE CENTRAL REGADO DE CHILE
Ruiz S.,Rafael;
Agricultura Técnica , 2000, DOI: 10.4067/S0365-28072000000400007
Abstract: a comparative study on nutritional aspects of the soil profile and plant nutrition in 5 thompson seedless grape (vitis vinifera) vineyards of different vigor and productivity was carried out for 4 years in the central valley of chile. monthly analytic determinations of total n, p, k and n reserve fractions such as arginine, total amino acids, and reserve carbohydrates in canes, shoots and roots were measured. soil profile fertility, physical soil properties, root system quality and nutritional levels on roots and aerial parts show satisfactory relations with vigor and/or productivity. conventional petiole analysis at the full bloom stage was not very efficient to separate the vineyards, whereas n reserves, carbohydrate reserves and an eventual p reserve found in the roots during the dormant period appeared closely related to vineyard condition and productivity. additionally, this study established seasonal variation curves for nutrients in the roots and aerial parts as well as the extraction of n, p, k, ca and mg in a variety of productivity-vigor situations. the relation between these cyclic changes of nutrients (including carbohydrates) and internal nutritional competition is discussed

MEDISAN , 2012,
Abstract: it is stated that currently most of the countries are absorbed in sector reforms in a globalized world, where the issue of public health costs is of concern for governments and health professionals. the optimal balance between the specificity of each function and the effective integration of the common aspects is a rule for the administration of the essential functions of public health. also, each function has its own functional identity and specific processes, which generate specific products and results that share common economic resources. also, they complement each other with the purpose of making decisions to become more complex.
Las técnicas constructivas en la formación de Al-Andalus
Azuar Ruiz, Rafael
Arqueología de la Arquitectura , 2005,
Abstract: The study of the constructive techniques in the formation of Al-Andalus is framed inside the debate about the transition from the late antiquity to the high Middle Ages and from the analysis of the processes that participate in the architectural production. Along the VIII and IX centuries, it is observed the difficulties in the recovery and standardization of the architectural demand where the projects of buildings in arranged masonry cohabit with the ones built in tapial (walls of compressed mud). This duality in the constructive techniques is an example of the slow and difficult the Islam formation progress of the peninsula that culminated in the X century with the Umayyad caliphate of Cordoba and that it supposed the development of a real constructive programme of Al-Andalus. El estudio de las técnicas constructivas en la formación de al-Andalus se enmarca dentro del debate sobre el paso de la Antigüedad Tardía a la Alta Edad Media y desde el análisis de los procesos que intervienen en la producción arquitectónica. A lo largo de los siglos VIII y IX, se observa las dificultadas en la recuperación y normalización de la demanda arquitectónica, en donde conviven los proyectos edilicios en sillería concertada con los construidos en tapial. Esta dualidad en las técnicas constructivas es un ejemplo de la lenta y difícil islamización de la península que culminó en el siglo X con el califato Omeya de Córdoba y que supuso el desarrollo de un verdadero programa arquitectónico andalusí.

MEDISAN , 2012,
Abstract: Se expone que actualmente la mayoría de los países se encuentran inmersos en reformas sectoriales ante un mundo globalizado, donde el tema de los gastos sanitarios preocupa a los gobiernos y profesionales de la salud. El balance óptimo entre la especificidad de cada función y la integración eficaz de los aspectos comunes constituye una regla para la administración de las funciones esenciales de la salud pública. Asimismo, cada función tiene identidad funcional propia y procesos específicos, los cuales generan productos y resultados particulares que comparten recursos económicos comunes; además, se complementan entre sí con el fin de tomar decisiones para ganar en complejidad. It is stated that currently most of the countries are absorbed in sector reforms in a globalized world, where the issue of public health costs is of concern for governments and health professionals. The optimal balance between the specificity of each function and the effective integration of the common aspects is a rule for the administration of the essential functions of public health. Also, each function has its own functional identity and specific processes, which generate specific products and results that share common economic resources. Also, they complement each other with the purpose of making decisions to become more complex.

Ruiz González, Rafael
Revista de Indias , 2002,
Abstract: This article studies the various laws regarding Brazilian Indians which were enacted as from the Union of Crowns (1580-1640). At that moment South Brazil became an important place within the political strategy of the Spanish Empire, as regards the development of a communication by land uniting Sao Paulo, Asunción and Potosí. This policy prospered between 1609 and 1616, but was interrupted when the war with the Low Countries recommenced. Este trabajo estudia las diferentes leyes que, con relación a los indios del Brasil, se dieron a partir del momento en que se realizó la unión de las Coronas (1580-1640). El sur del Brasil pasó a tener un lugar destacado dentro de la estrategia política del imperio espa ol, buscando el desarrollo del camino terrestre entre S o Paulo, Asunción y Potosí. Esa política, que encontró su auge entre los a os 1609-1616, tuvo que ser interrumpida más tarde con la reanudación de la guerra con los Países Bajos.
