Calzadilla Bertot,Luis; Vilar Gómez,Eduardo; Lincheta Enriquez,Laritza;
Revista Cubana de Medicina , 2011,
Abstract: the prognostic models are a significant pillar in assessment of patients presenting hepatic cirrhosis, mainly at moment to make a decision related to liver transplantation. the two more used models at international level, the child pugh turcotte and the model for end stage liver disease ( meld) have advantages and disadvantages in its approximation to patients. the aim of present paper was to review these prognostic models used in the end-terminal liver disease, as well as to compare the above mentioned models on the base of the design, predictive effectiveness and practical application. we conclude that both models are useful to predict mortality in patients presenting with hepatic cirrhosis and also that more future researches must to be performed to improve its discriminatory power.
Modelos pronósticos para la cirrosis hepática Prognostic models for hepatic cirrhosis

Revista Cubana de Medicina , 2011,
Abstract: Los modelos pronósticos representan un pilar importante en la evaluación de los pacientes con cirrosis hepática, sobre todo a la hora de tomar decisiones como el trasplante hepático. Los 2 modelos más utilizados al nivel mundial, el Child Pugh Turcotte y el Model for end stage liver disease (MELD), presentan ventajas y desventajas en su aproximación a los pacientes. El objetivo de este trabajo fue revisar estos modelos pronósticos utilizados en la enfermedad hepática terminal, así como comparar el modelo MELD y el Child Pugh Turcotte sobre la base del dise o, eficacia predictiva y aplicación practica. Se concluye que ambos modelos son útiles para predecir la mortalidad en los pacientes con cirrosis hepática y que se deben realizar futuras investigaciones para mejorar su poder discriminativo.

Abstract: the aim of this paper is to make available, through an empirical study, whether the introduction of a quality management system in the olive oil extraction process according to the norm iso 9001:2000 would have a positive impact on the quality of the final product. in order to achieve this objective, the data analyzed were collected by means of questionnaires sent to a sample of 2.800 olive oil plants, of which 501 answered to it. the statistical analysis of the data collected allowed classifying the olive oil plants in five clusters according to different standards of quality, as follows: very high, high, medium, low and very low. the membership to one or another cluster was determined by the involvement of each olive oil plant with six factors: characteristics of the milling process, the existence of complementary management methods, implementation of formative actions, treatment of basic processes, availability of alternative processes and classification methods for the products. the results obtained show that the introduction of a quality management system according to the norm iso 9001:2000 in the olive oil extraction process allows a percentage increase in the obtaining of a product of quality.

Vilar Gómez,Eduardo; Grá Oramas,Bienvenido; Llanio Navarro,Raimundo; Arús Soler,Enrique;
Revista Cubana de Medicina , 2003,
Abstract: approximately 80 % of hepatitis c evolves to chronicity. the epidemiological and viral factors as well as those of the guest take part in the progression of the disease. the behavior of the epidemiological variables associated with chronic hepatitis c was described and the possible association of these ones with the intensity of fibrosis was identified. 80 patients with hepatitis c were studied and the intensity of fibrosis was determined by the metavir scoring system. they were grouped into absence or little fibrosis (f0-f1) and marked fibrosis (f2-f4) seeking for the possible statistical association with the epidemiological factors. a significant association was found among the infection's oldness estimate, the way it was acquired, the patient's age on catching it and the intensity of fibrosis. the progression of hepatits c may be determined by some epidemiological factors influencing decisively the natural history of the disease.

Revista Cubana de Medicina , 2004,
Abstract: a review was made to explain how the diverse cellular processes occurring in the severely damaged liver tissue and in the mesenteric circulation influence on the different systemic alterations appearing in acute liver failure, and the close relation existing among them. the acute liver failure is a clinical syndrome resulting from a mass liver necrosis generating progressive dysfunction of the organ with the presence of deep alterations in its detoxicating, metabolic, sinthesizing and excreting functions.the hypothesis of critical mass, as well as that on endotoxins-cytokines and vasoactive substances explain somehow the different molecular changes supporting the physiopathological bases of this complex entity.
Incidencia del modo de explotación del olivo sobre la renta neta del olivicultor. Estrategias para el cultivo extensivo en el contexto de la posible ausencia de subvenciones
Vilar Hernández, Juan,Velasco Gámez, María del Mar,Puentes Poyatos, Raquel
Grasas y Aceites , 2010, DOI: 10.3989/gya.010210
Abstract: This article compares the competiveness and profit margins of different cultivation systems and analyzes these circumstances for this agricultural activity and at the same time gives some different alternatives in order to help to improve the net profit from traditional olive tree cultivation. These different strategies are always based on field concentration, work force and innovation activity. El presente trabajo trata de analizar la competitividad, en términos de rentabilidad, de las explotaciones de olivar tradicional en relación con las nuevas modalidades de cultivo de mayor densidad de plantación, a la vez que se enuncian una serie de alternativas, que podrían ayudar a consolidar su futuro, vía incremento de rentabilidad. Los resultados muestran como las explotaciones tradicionales en ausencia de ayudas son menos rentables que las intensivas y superintensivas, por lo que sería conveniente que adoptaran algunas de las estratégicas de mejora de la competitividad que aquí se enuncian, consistentes principalmente en la innovación incremental, la agrupación, o la explotación conjunta.

Revista Cubana de Medicina , 2007,
Abstract: Las tasas de seroconversión del antígeno e alcanzadas con los antivirales actuales no sobrepasan el 35 %. La combinación de inmunomodulador y antiviviral ha sido teóricamente la estrategia más aceptada en los últimos a os; sin embargo, los resultados en la práctica clínica han sido contradictorios. Se realizó el presente trabajo para evaluar la eficacia y seguridad de un esquema de tratamiento prolongado durante 52 sem con interferón alfa-2b más lamivudina en pacientes con hepatitis crónica B y antígeno e positivo. Se estudiaron 46 pacientes asignados aleatoriamente: 23 recibieron 150 mg diarios de lamivudina por 4 sem, lamivudina más interferón alfa-2b (10 MU en días alternos) por 24 sem, seguido de lamivudina en la misma dosis y frecuencia hasta completar las 52 sem. Otros 23 recibieron 150 mg diarios de lamivudina por 4 sem y lamivudina más interferón alfa-2b (5 MU en días alternos) durante 52 sem. Se encontró que las tasas de seroconversión del antígeno fueron similares en ambos grupos. Una proporción significativa de pacientes con tratamiento combinado prolongado logró negativizar el ADN viral (52 % frente al 26 %, p=0,06) y el antígeno de superficie (48 % frente al 26 %, p=0,11), comparado con los controles. La mejoría en el índice de actividad histológica fue observada en el 48 % de los pacientes tratados con tratamiento combinado prolongado frente al 22 % de los controles (p=0,06). Se concluyó que el tratamiento prolongado deerferón y lamivudina durante 52 sem puede brindar beneficios clínicos en las tasas de pérdida sostenida del ADN viral, el antígeno de superficie y en el índice de actividad histológica. The seroconversion rates of e antigen attained with the current antivirals do not exceed 35 %. The combination of immunomodulator and antiviral has been theoretically the most accepted strategy in the last five years; however, the results in clinical practice have been contradictory. This paper is aimed at evaluating the efficacy and security of a treatment scheme prolonged for 52 weeks with alpha-2b interferon plus lamivudine in patients with e antigen positive chronic hepatitis B. 46 patients selected at random were studied: 23 received 150 mg of lamivudine daily during 4 weeks, lamivudine plus alpha-2b (10 MU every other day) for 24 weeks, followed by lamivudine in the same dose and frequency until completing the 52 weeks. Other 23 were administered 150 mg of lamivudine daily for 4 weeks plus alpha 2b interferon (5 MU every other day) during 52 weeks. It was found that the antigen seroconversion rates were similar in both groups. A marked

Abstract: Aproximadamente 80 % de la hepatitis C evoluciona a la cronicidad. Factores como los epidemiológicos, virales y del huésped intervienen en la progresión de la enfermedad. Se describió el comportamiento de variables epidemiológicas asociadas a la hepatitis crónica C y se identificó la posible asociación de estas con la intensidad de la fibrosis. Se estudiaron 80 pacientes con hepatitis C. Se determinó la intensidad de la fibrosis por el sistema de puntuación METAVIR. Se agruparon en: ausencia o poca fibrosis (F0-F1) y fibrosis marcada (F2 a F4) buscando la posible asociación estadística con los factores epidemiológicos. Se halló asociación significativa entre el estimado de antigüedad de la infección, la vía de adquisición y la edad al contraerla con la intensidad de la fibrosis. La progresión de la hepatitis C puede estar determinada por algunos factores epidemiológicos que influyen de forma decisiva en la historia natural de la enfermedad.

Bases fisiopatológicas de la insuficiencia hepática aguda Physiopathological bases of acute liver failure
Eduardo Vilar Gómez,Bienvenido Grá Oramas,Raimundo Llanio Navarro,Enrique Arús Soler
Revista Cubana de Medicina , 2004,
Abstract: Se hace una revisión para explicar cómo influyen y la estrecha relación que tienen los diversos procesos celulares que ocurren en el tejido hepático, severamente da ado, y en la circulación mesentérica con las distintas alteraciones sistémicas que aparecen en la insuficiencia hepática aguda, síndrome clínico resultado de una necrosis hepática masiva que genera disfunción progresiva del órgano con la presencia de profundas alteraciones en sus funciones detoxificadora, metabólica, sintetizadora y excretora. La hipótesis de la masa crítica, así como la de las endotoxinas-citoquinas y sustancias vasoactivas explican de cierta forma los diferentes cambios moleculares que sustentan las bases fisiopatológicas de esta compleja entidad. A review was made to explain how the diverse cellular processes occurring in the severely damaged liver tissue and in the mesenteric circulation influence on the different systemic alterations appearing in acute liver failure, and the close relation existing among them. The acute liver failure is a clinical syndrome resulting from a mass liver necrosis generating progressive dysfunction of the organ with the presence of deep alterations in its detoxicating, metabolic, sinthesizing and excreting functions.The hypothesis of critical mass, as well as that on endotoxins-cytokines and vasoactive substances explain somehow the different molecular changes supporting the physiopathological bases of this complex entity.

Revista de Estudios Cooperativos , 2009,
Abstract: Este artículo trata de mostrar cómo el buen gobierno de las sociedades se ha de dirigir hacia un modelo de gobierno corporativo stakeholders, donde las sociedades cooperativas pueden servir de referencia en la medida que este modelo de gobierno corporativo es intrínseco a su razón de ser. Pondremos de manifiesto, cómo los Códigos de buen gobierno publicados hasta el momento en Espa a no se ajustan a este enfoque stakeholders y no son de aplicación plena a sociedades no mercantiles, como las sociedades cooperativas./This article aims to show how the governance of societies has been directed toward a model of corporate governance stakeholders, where cooperative societies can serve as a reference to the extent that this model of corporate governance is intrinsic to its purpose. I will be shown how the codes of good governance published so far in Spain are not in line with this approach and stakeholders are not fully applied to non-market societies, such as cooperative societies.
