Abstract: the study of tactics for the root-knot nematode management in vegetable production under crop protected systems has been increased in cuba in the last decade. the main goal of this work was to assess the relationship of ecomic?, a commercial product containing several mycorrhizal fungi, and a cuban population of meloidogyne incognita in tomato (lycopersicon esculentum mill var. vyta). the experiment was carried out in a green house at censa using a completely randomized design. ecomica was inoculated by seed pelleting or mixed with the seedbed substrate. the nematode dose used was 1.5 egg-j2. g soil-1. gall index, infective juveniles in soil and root weight were evaluated. the percentage of colonization, the visual density and the mycellial weight were also estimated. ecomica was shown to benefit root development despite the high value of the gall index (gi=4) in the inoculated plants. root development was lower in the untreated plants with a gi=5. a decreased number of infective juveniles was observed in the soil with mycorrhized plants. the micorrhizal colonization was not affected by nematode establishment.

Open Journal of Metal (OJMetal) , 2013, DOI: 10.4236/ojmetal.2013.32a1005
Abstract: Soil contamination with heavy metals has become a world-wide problem, leading to the loss in agricultural productivity. Plants have a remarkable ability to take up and accumulate heavy metals from their external environment and it is well known that high levels of heavy metals affect different physiological and metabolic processes. Brassinosteroids are considered as the sixth class of plant hormones and they are essential for plant growth and development. These compounds are able of inducing abiotic stress tolerance in plants. In this paper, information about brassinosteroids and plant responses to heavy metal stress is reviewed.

Abstract: Introduction Cardiovascular diseases constitute the first cause of death in Cuba. In orderto assess the cardiovascular risk, several risk models have been created.One of them was recently proposed by the World Health Organization(WHO).Objective To determine the global cardiovascular risk in the Health Area population ofMártires del Corynthia in the Plaza de la Revolución municipality of Havana.Method A descriptive, cross-sectional study of a population sample from 40 to 70years was conducted. We included 1 287 randomized subjects chosenthrough double-stage cluster sampling and for the individual selectionthrough simple randomized sampling. The variables used were age, sex,educational level, occupation, smoking habit, diabetes, obesity, arterialpressure, total cholesterol and triglycerides. Percentages were calculated tosummarize the qualitative data obtained.Results The WHO risk model was used. 93,6% of subjects were classified as low risk;intermediate risk 4%; high risk 1,2%; very high risk 0,6% and in very veryhigh risk 0.5 %. The highest risk categories prevailed in men and it was increasedaccording to age. The risk factors prevalence found in falling orderwas: high triglyceride levels, arterial hypertension, smoking habit, obesity,high cholesterol levels and diabetes.Conclusions The low Global Cardiovascular Risk levels found in our population could bedetermined by the risk model used, which underestimates our population'sreal risk.

Abstract: a methodology for scientific analysis and solution of problems was designed on the basis of advanced quality tools. it was applied to a swine production process of raw material supplier for the manufacture of drugs. as a result of the analysis of the main process problem, the low availability of pigs, which fulfilled the health requirements as donors of mpf and most influential in causing respiratory diseases in swine units in the country studied, was identified. critical success factors of this production system coincided with the probable causes of the main problems identified, increasing yield and consistency of the process with the most suitable animals a year, reducing losses by diseases, primarily respiratory, changing current productive paradigm and having suppliers selected and approved to meet a new productive paradigm. among the alternatives or changes were early slaughter and design of a supplier management process, with selection of official suppliers evaluated with productive paradigm focused on the production of raw material for the manufacture of drugs. to verify and monitor the effectiveness of the redesigned technology system, a system of quality costs was developed, allowing the distribution of costs among the planned activities to ensure and assess the production and failures caused by poor quality. the application of this system shows that in the period, after the redesign of the process, there was a progressive reduction of the costs by failures, achieving a balance between them and evaluation and prevention costs, so they can begin to reduce expenses in these two categories. the results obtained with the swine production process show the feasibility of the methodology designed, since the scientific analysis performed, there was a positive impact in its efficiency and consistency, helping to maintain the quality levels of pharmaceutical products.

Abstract: INTRODUCTION: Acute myocardial infarction is one of the leading causes of death in the world. This is also true in Cuba, where no national-level epidemiologic studies of related mortality have been published in recent years. OBJECTIVE Describe acute myocardial infarction mortality in Cuba from 1999 through 2008. METHODS A descriptive study was conducted of persons aged >25 years with a diagnosis of acute myocardial infarction from 1999 through 2008. Data were obtained from the Ministry of Public Health's National Statistics Division database for variables: age; sex; site (out of hospital, in hospital or in hospital emergency room) and location (jurisdiction) of death. Proportions, age- and sex-specific rates and age-standardized overall rates per 100,000 population were calculated and compared over time, using the two five-year time frames within the study period. RESULTS A total of 145,808 persons who had suffered acute myocardial infarction were recorded, 75,512 of whom died, for a case-fatality rate of 51.8% (55.1% in 1999-2003 and 49.7% in 2004-2008). In the first five-year period, mortality was 98.9 per 100,000 population, falling to 81.8 per 100,000 in the second; most affected were people aged >75 years and men. Of Cuba's 14 provinces and special municipality, Havana, Havana City and Camagüey provinces, and the Isle of Youth Special Municipality showed the highest mortality; Holguín, Ciego de ávila and Granma provinces the lowest. Out-of-hospital deaths accounted for the greatest proportion of deaths in both five-year periods (54.8% and 59.2% in 1999-2003 and 2004-2008, respectively). CONCLUSIONS Although risk of death from acute myocardial infarction decreased through the study period, it remains a major health problem in Cuba. A national acute myocardial infarction case registry is needed. Also required is further research to help elucidate possible causes of Cuba's high acute myocardial infarction mortality: cardiovascular risk studies, studies of out-of-hospital mortality and quality of care assessments for these patients.

Abstract: Dada la extraordinaria importancia ecológica y económica de los hongos micorrízicos arbusculares (HMA), en Cuba y otros países, se han dado pasos acelerados para poner en práctica su uso como biofertilizante. En el presente trabajo se realizó un estudio comparativo del comportamiento de seis cepas de HMA, en su interacción con plántulas de tomate de la variedad Amalia , mediante indicadores fúngicos, agronómicos y bioquímicos con el objetivo de evaluar las diferencias existentes en los patrones de colonización de las distintas cepas y seleccionar la más promisoria para este cultivo en las condiciones estudiadas. Las cepas de HMA estudiadas fueron Glomus fasciculatum, G. clarum, G. mosseae, Glomus sp.1, G. intrarradices y Acaulospora scrobiculata. A los 18 y 32 días de germinadas las semillas se evaluó: altura; masa fresca y seca (aérea, radical y total) y la actividad específica radical de quitinasa, β-1,3-glucanasa y fenilalanina amonio liasa (PAL); así como las variables fúngicas colonización (%) y densidad visual (%) a los 32 días. En sentido general, se encontró un efecto positivo de la inoculación sobre las plántulas de tomate con respecto a los controles, expresado en los indicadores agronómicos y fúngicos estudiados. Los resultados mostraron además respuestas diferenciadas de las plántulas de tomate en función de las cepas de HMA inoculadas, con relación a las actividades enzimáticas, destacándose la cepa Glomus fasciculatum como la más efectiva para esta interacción en las condiciones estudiadas.

Abstract: La hipertensión arterial es la enfermedad que con mayor frecuencia tienen que enfrentar el médico y la enfermera de la atención primaria. Su prevalencia está entre el 28 y 32 % al adoptar cifras definitorias de 140/90 mmHg, así aproximadamente 1 de cada 3 cubanos es hipertenso. La magnitud de este problema de salud provoca la búsqueda de tratamientos y métodos que contribuyan a su disminución y es por eso que la adherencia terapéutica tiene gran importancia en su control. Se realizó un estudio descriptivo de corte transversal con el objetivo de identificar conocimientos, creencias y prácticas sobre adherencia terapéutica en pacientes hipertensos del policlínico "Corinthya" , de septiembre a diciembre de 2003. Se aplicó una encuesta que incluyó como variables: conocimientos acerca de la hipertensión arterial, creencias implícitas en los componentes del modelo de creencias en salud y prácticas relacionadas con el tratamiento. Más de la mitad de los hipertensos (55.2 %) no conocía los factores que propician la hipertensión arterial. Sólo el 51, 6 % tenían la percepción de riesgo necesaria, lo cual repercutió negativamente en sus prácticas. Aproximadamente la mitad de los pacientes asistían sistemáticamente a consultas, cumplían su tratamiento y refirieron haber recibido suficiente información. Se puede concluir que la falta de adherencia al tratamiento de los pacientes se debió mayormente a que no recibieron educación suficiente y adecuada y no tuvieron incorporadas creencias en salud que le permitieran modificar sus conductas o prácticas en salud.
