Características clinicoepidemiológicas del lupus eritematoso sistémico. Hospital Manuel Uribe ángel de Envigado
Antonio de Castro,Carlos Alviar,Miguel Cuevas,Ricardo Cruz
Iatreia , 2001,
Abstract: El lupus eritematoso sistémico (LES) es relativamente frecuente e incapacitante, pero excepcionalmente mortal. Conscientes de lo anterior y de la falta de información epidemiológica al respecto en nuestra región, es de suma importancia analizar su comportamiento con el fin de obtener indicadores que brinden un conocimiento más adecuado de ella en nuestro medio, determinando cuáles son las formas de presentación clínica más frecuentes; así se podría disponer de información que guiara al clínico en un diagnóstico temprano y un tratamiento eficaz, con lo que se reduciría el riesgo de complicaciones y de letalidad prevenibles.
Dichloridobis(methanol-κO)[cis-(±)-2,4,5-tris(pyridin-2-yl)-2-imidazoline-κ3N2,N3,N4]ytterbium(III) chloride
Alberto Baez-Castro,Herbert Höpfl,Miguel Parra-Hake,Adriana Cruz-Enriquez
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812022052
Abstract: In the crystal structure of the title complex, [YbCl2(C18H15N5)(CH3OH)2]Cl, the pseudo-pentagonal–bipyramidal coordination geometry of the YbIII cation is composed of three N atoms from one cis-(±)-2,4,5-tris(pyridin-2-yl)imidazoline (HL) ligand, two O atoms from two methanol molecules and two Cl anions. Chains are formed along [010] through N—H...Cl, O—H...Cl and O—H...N hydrogen bonds.
Histological comparison of the alar nasal cartilages in unilateral cleft lip
Modolin, Miguel;Baracat, Glaucia Zeferino;Kamakura, Luiz;Cintra Jr., Wilson;Cruz, Luiz Gustavo Balaguer;Ferreira, Marcos Castro;
Revista do Hospital das Clínicas , 2002, DOI: 10.1590/S0041-87812002000400004
Abstract: patients with unilateral cleft lip display characteristic nasal changes that are independent of the degree of deformity. defenders of the intrinsic theory consider these deformities to be due to embryogenic alterations of the alar nasal cartilages. those that propose the extrinsic theory defend the thesis that the deformity is due to disorganization of the perioral muscles deformed by the cleft. the purpose of this study is to contribute histological evidence to help clarify the issue. patients and methods: specimens of the lateral portion of both the healthy and the cleft side of the alar cartilages were obtained from 18 patients. these uniformly cut specimens were stained by hematoxylin and eosin. samples from 2 patients were excluded due to imperfections. the same pathologist examined all the slides. he was unaware of the origins of the specimens; he counted the number of chondrocytes and quantified the cartilage matrixes. results: all data was analyzed statistically, and no significant statistical differences were apparent, either in the number of chondrocytes or the cartilage matrix between the healthy side and the cleft side. discussion: these results apparently support the group that defend the extrinsic theory; nevertheless, the doubt about the composition of the cartilage matrix remains, not only concerning the glycosaminoglycans that compose them, but also regarding elastin and collagen and its linkages that can cause different degrees of collagen consistency.
Evaluación preliminar de la penetración eólica en el sistema eléctrico de la Isla de la Juventud

Ingeniería Energética , 2010,
Abstract: At many countries there is great areas where wind resource are very grateful but the electrical network isweak. At these areas the network capacity could be a limit to exploitation of wind resource.There are twomain problems related with the associated power of wind resurge and the network weak. First, it is relatedwith steady state voltage level: when demand is low the voltage level could increase more than permittedlimits if the energy production is high. The second problem is related with flicker voltage: the wind resourceis not constant and the disconnection of the wind turbines could cause flicker voltage more than permittedlimits.In Cuban electric system the presence of weak network is normally and different problems likehurricanes or work this electric system require to divide on electric subsystems with possible highcontribution of wind generation. The preliminary analysis at one zone of Cuban′s archipelago from the pointof view of wind penetration is presented in this paper.

Abstract: in portugal, stroke is considered the leading cause of death and disability associated with cognitive and motor sequelae. the incidence of dysphagia ranges from 22% to 65% of patients (ramsey, smithard and kalra, 2003). several studies reveal that 30 to 40% of institutionalized elderly people have swallowing disorders, which results in a high incidence of complications due to aspiration (world gastroenterology organization, 2004). based on these assumptions, a systematic review was performed to minimize the risk of ad hoc evaluation and by identifying the available low cost and easy access resources in order to enhance health gains. the methodology was guided by cochrane handbook and was designed to answer the following question: “what methods of non-invasive evaluation of dysphagia in people with neurological disease with demonstrated validity and reliability are published?” therefore we conducted a search for primary studies, published since 2005, in the most relevant computerized databases. from that search, we identified two studies with the results of the application of two distinct scales used in the diagnosis of dysphagia in stroke survivors (in acute and / or rehabilitation), one of which also assessed the risk of aspiration. the results may predict high gains in health with the application of these scales, although further studies are needed to obtain a substantial sample.
The War on Terror in East Asia: From Cooperative Security to Preemptive Defense
Renato Cruz de Castro
Kasarinlan : Philippine Journal of Third World Studies , 2003,
Abstract: This article traces the evolution of the American-led global campaign against international terrorism with a specific focus on East Asia. It notes that at the initial stage of the campaign, the United States has been very pragmatic and circumspect when it cooperated with its Asian allies in neutralizing terrorist groups and other transnational criminals. The campaign generated a positive trend towards cooperative security as Washington provided military and intelligence assistance to several countries threatened by local and international terrorist movements. The initial phase of the war on terror in East Asia had also produced a rapprochement between the US and China whose relations were strained during the early part of 2001. However, Washington’s release of a new national security strategy in September 2002 has radically transformed the war on terror in East Asia and might create some problems in America’s efforts to foster cooperative security as states in the region are responding adversely to the strategy of preemptive defense. It is only natural for the East Asian states to react negatively to this development and that the US will do well to take into account these reactions in justifying and making the new defense posture acceptable to the member-states of the international community.
Una mirada a la ingeniería clínica desde las publicaciones científicas
Cruz,Antonio Miguel;
Biomédica , 2010,
Abstract: the aim of this paper was to characterize clinical engineering from the perspective of scientific publications. first of all, the most significant factors that influence the change in health systems are briefly exposed. then, clinical engineering is defined and its main functions and evolution within the development of the health system is explained. finally, the author describes the state of the field from the viewpoint of the scientific publications; an apparent lack of interest in the engineering community to publish scientific research was observed. this behavior can be seen in the clear declining tendency in the number of citations and the number of publications (in volume or quantity) in major scientific journals in the field. finally, current challenges and future developments must be addressed to accomplish a better positioning of the specialty in the publishing world.

Cruz,José Miguel;
Revista Panamericana de Salud Pública , 1999, DOI: 10.1590/S1020-49891999000400009
Abstract: this article looks at eight cities in latin america and spain and compares the chances of and variables associated with being a victim of various kinds of urban violence. the analysis was done using data from the activa multicenter study, which was coordinated by the pan american health organization in 1996. the study sample consisted of 10 821 persons who were representative of residents between the ages of 18 and 70 in eight metropolitan areas of latin america and spain: rio de janeiro, brazil; salvador, brazil; santiago, chile; cali, colombia; san josé, costa rica; san salvador, el salvador; caracas, venezuela; and madrid, spain. the results show that the likelihood of being a victim of different types of violence varies from city to city. the variables associated with a greater likelihood of being a victim in most-though not all-of the cities are sex, age, and consumption of alcohol.
El impacto psicosocial de la violencia en San Salvador
Cruz,José Miguel;
Revista Panamericana de Salud Pública , 1999, DOI: 10.1590/S1020-49891999000400013
Abstract: this study had two objectives: (1) to describe the levels of victimization of salvadorians due to criminal violence, and the population groups most affected by it; (2) to learn if these levels of victimization are related to the presence of norms, attitudes, and behaviors that encourage the occurrence of violence. for this purpose data from the activa project of el salvador were used. the project was carried out by the university institute of public opinion during october and november 1996, with a sample of 1 290 personal interviews that were presumed to be representative of people between 18 and 70 years of age living in the metropolitan area of san salvador. the sample was obtained through multistage probability sampling. the results show that the level of victimization from violence is quite high in san salvador and that it especially affects adult and young men. the results also indicate that persons who have been victims of serious aggression tend to show, more frequently than average, norms justifying and approving the use of violence, a tendency to use weapons, and aggressive behaviors toward other people.
Violencia y democratización en Centroamérica: el impacto del crimen en la legitimidad de los regímenes de posguerra Violence and democratization in Central America: the impact of crime in the legitimacy of post-war regimes
José Miguel CRUZ
América Latina Hoy , 2010,
Abstract: El propósito fundamental del artículo es mostrar que los elevados niveles de la violencia común y de la delincuencia que afectan en la actualidad a los países latinoamericanos, especialmente a los países centroamericanos de posguerra, constituye un obstáculo y una amenaza para los procesos de democratización. Esto porque la violencia criminal erosiona el apoyo ciudadano a los regímenes surgidos de las transiciones políticas y resta legitimidad al sistema político. El artículo parte de los resultados de una serie de encuestas llevadas a cabo con más de 6.700 ciudadanos en países centroamericanos en situación de posguerra (Guatemala, El Salvador y Nicaragua) en 1999 y se analiza la vinculación entre los niveles de victimización y de percepción de inseguridad pública con el nivel de apoyo político para el sistema. The main purpose of this article is to show that the high levels of common violence and crime, which currently affect Latin American countries, especially post-war Central American ones, represent a threat and obstacle to democratization processes. This is so, because common violence erodes the citizens’ support to the regimes emerged from the political transitions and deteriorates the legitimacy of the political system. The article is based on the results of a series of surveys conducted with more than 6.700 citizens who live in post-war Central American countries (Guatemala, El Salvador and Nicaragua) during 1999, as the link between victimization levels, perception of public insecurity and the level of political support for the system is analyzed.
