Abstract: Se estudiaron 40 pacientes del sexo femenino, premenopáusicas, menores de 45 a os, con diagnóstico establecido de artritis reumatoidea según criterios del Colegio Americano de Reumatología y todas con tratamiento de esteroides, con un equipo de densitometría ósea por ultrasonido del calcáneo. Al analizar el promedio de t-score (como marcador de osteoporosis), encontramos que el valor más bajo de fue de - 4,5 y el máximo de -1,5. Se empleó el test estadístico t -Student para comparar los promedio del t-score según: dosis, tiempo de tratamiento con esteroides y tiempo de evolución de la enfermedad. Se encontró osteoporosis en 23 pacientes que tomaban más de 20 mg de esteroides; en 27 con más de 5 a os de tratamiento con esteroides; y en 23 con más de 5 a os de evolución de la enfermedad. Al explorar el antecedente de fractura y relacionarlo con el tiempo de tratamiento y la dosis de esteroides encontramos que 9 pacientes (81,8 %) con más de 5 a os de tratamiento y 6 (54,5 %) con más de 20 mg de esteroides tienen antecedente de fractura. 40 premenopausic female patients under 45 with established diagnosis of rheumatoid athritis according to the criteria of the American College of Rheumatology were studied.

Abstract: Se estudió un grupo de 52 mujeres en etapa premenopáusica con diagnóstico de bocio tóxico difuso y un grupo control constituido por 54 mujeres sanas. Se encontró que la media para la edad en el grupo 1 fue de 35,7 a os y para el grupo 2, de 34,83 y la media en las 106 pacientes fue de 35,29 a os. Se midió la densidad mineral ósea mediante un equipo de densitometría ósea por ultrasonido del calcáneo (SONOST 2000 Medison). Se evidenció que el número de casos sin alteración ósea fue mayor en el grupo control: 40 casos (74,0 %), contra 8 (15,4 %) del grupo 1, y este grupo tuvo el mayor porcentaje de casos con osteopenia (22 [42,3 %]) y osteoporosis (22 [42,3 %]). Al utilizar estudios no paramétricos como el test de Rangos con signos de Wilcoxon encontramos que existe diferencia significativa entre el estudio inicial y el final, según los resultados de la osteosonometría. La osteosonometría fue normal al a o del tratamiento en 19 pacientes por encima de la realizada inicialmente, y la osteoporosis desapareció en 10 pacientes. Se halló que los 16 que se mantuvieron hipertiroideos al realizarle el estudio final de osteosonometría, presentaban osteopenia u osteoporosis. Mientras que en los 25 pacientes eutiroideos la osteosonometría fue normal. Al final, 27 sujetos tuvieron un resultado en la osteosonometría en el rango normal, 19 por encima del estudio inicial. En los sujetos a los que se les aplicó el esquema de tratamiento 3, en 15 la osteosonometría fue normal, así como que fue el grupo que menos pacientes osteoporóticos tuvo, con 2 solamente, aunque con el tratamiento 2 la respuesta fue bastante adecuada, no así con el tratamiento 1 2 women in premenopausal stage diagnosed as diffuse toxic goiter and a control group including 54 healthy women were studied.

Abstract: a cross-sectional descriptive study of 340 persons assigned to two groups, with and without family history of diabetes mellitus type 2 (dm2), was carried out. the objective was to detect whether those persons with family history of dm2 had more hyperinsulemia, metabolic syndrome, associated cardiovascular risk factors and target organ lesions, expressed in left ventricle hypertrophy, than subjects without diabetes family history. the result was that hyperinsulemia was present in 96 patients with family history of dm2 (56,5 %) and significance level of p= 0,001. metabolic syndrome was more frequent in subjects with family history of dm2 (90) for 52,9 % of cases and p= 0,000. hypertriglyceridemia was both the most noticeable marker of the metabolic syndrome and the most statistically significant risk factor in subjects with family history of dm2 (96 , 52,9 % of cases and p= 0,000). left ventricle hypertrophy was associated as target organ lesion expression to subjects with family history of dm2 (36: 21,2 % and p=0,043). it was concluded that subjects with family history of dm2 are more likely to have hyperinsulinemia, metabolic syndrome, cardiovascular risk factors and target organ lesions than those persons without such a family history of dm2.

MEDICC Review , 2012,
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: ANTECEDENTES: la cardiopatía isquémica es una de las primeras causas de muerte internacionalmente, y para valorar el riesgo cuantitativo de padecerla, se han creado tablas de riesgo, y una de las más empleadas ha sido la tabla de riesgo cardiovascular de Framingham. En Cuba son escasos los estudios sobre valoración de riesgo cardiovascular total. OBJETIVO: determinar el nivel de riesgo cardiovascular total en una población de trabajadores. MéTODOS: se realizó un estudio piloto descriptivo en 301 trabajadores del Hotel "Meliá Cohíba". Las variables utilizadas: hipertensión arterial y las correspondientes a la tabla de riesgo de Framingham (demográficas, hábitos de fumar, presión arterial sistólica, diabetes, colesterol total, colesterol HDL e hipertrofia ventricular izquierda). Se calculó el riesgo cardiovascular total de cada trabajador. Se utilizaron como medidas de resumen, las frecuencias relativas en por ciento, calculadas mediante el programa SPSS, versión 13,0 y el calificador de riesgo para obtener el puntaje en cada individuo. Los resultados se expusieron en tablas para su análisis y discusión. RESULTADOS: el riesgo de padecer una enfermedad cardiovascular en los próximos 10 a os fue mayor en hombres, y aumentó proporcionalmente con la edad. El riesgo cardiovascular fue considerado bajo en el 80,4 % del total, menor en mujeres. La dislipidemia fue el factor de riesgo cardiovascular más frecuente en esta población, seguida del hábito de fumar (43,2) y la hipertensión arterial (15 %). CONCLUSIONES: el bajo nivel de riesgo cardiovascular global en esta población pudiera estar determinado por la edad de la población estudiada. Los factores de riesgo más prevalentes en los casos estudiados fueron la dislipidemia, el hábito de fumar y la HTA. BACKGROUND: ischemic heart disease is one of the first causes of death in the world. To assess the quantitative risk of suffering from it, risk tables have been created and Framingham's cardiovascular risk table has been one of the most used so far. In Cuba, a few studies on the assessment of total cardiovascular risk have been conducted. OBJECTIVE: to determine the total cardiovascular risk level in a population of workers. METHODS: a pilot descriptive study was carried out among 301 workers of "Meliá Cohiba" Hotel. The variables used were arterial hypertension and the corresponding to Framingham's risk tables (demographic, smoking habit, systolic arterial pressure, diabetes, total cholesterol, HDL cholesterol and left ventricular hypertrophy). The total cardiovascular risk of each worker was calculated. The rel

Abstract: Antecedentes: En Cuba, las enfermedades del corazón constituyen la primera causa de muerte desde hace más de 4 décadas. No se cuenta con estudios que permitan conocer la prevalencia de las enfermedades del corazón a escala poblacional de país. Objetivo: Determinar la magnitud de la morbilidad por enfermedades del corazón en Cuba. Métodos: Se realizó un estudio transversal en la población cubana de 15 a os y más, a o 2001. Dise o muestral: estratificado y por conglomerados bietápico. Las 14 provincias del país y el municipio Isla de la Juventud conformaron los estratos. Se utilizó un factor de ponderación que tomó en consideración la edad y el sexo. Fueron encuestados 22 851 individuos. Variables utilizadas: sociodemográficas, económicas, y enfermedades crónicas no trasmisibles seleccionadas. Programas estadísticos utilizados: SAS y SUDAAN. Se estimaron las proporciones, las medias y los intervalos de confianza al 95 %. Resultados. Refirieron padecer enfermedades del corazón un 7,4%, estas fueron más frecuentes en mujeres y se incrementaron con la edad siendo el grupo de 75 y + y el de 65-74 los más afectados (31,48% y 21,91 respectivamente). Las provincias con mayores prevalencias fueron Ciudad La Habana, Matanzas y Villa Cara. Las enfermedades del corazón más prevalentes fueron: cardiopatía isquémica (aportó el 60% del total) e insuficiencia cardiaca (más frecuente en mujeres). Conclusiones. -La cardiopatía isquémica fue la enfermedad del corazón más prevalente, siendo el sexo femenino el más afectado, incrementándose con la edad. Background: Heart diseases in Cuba have been the first cause of death for more than 40 years. There are not studies available that show the prevalence of heart diseases at population scale in the country. Objective: To determine the magnitude of heart disease morbidity in Cuba. Methods: A crosswise study was carried out in the Cuban population aged 15 years and over in the year 2001. Sampling design: stratified design by two-phase clusters. All the provinces and the special municipality Isle of Youth made up the strata. The weighing factor took into account age and sex. A total number of 22 851 subjects were surveyed. Variables: socio-demographic, economic and selected non-communicable chronic diseases. Statistical programs used: SAS and SUDAAN. Ratios, means and 95% confidence intervals were estimated. Results: Of the surveyed population, 7,4% stated that they suffer from heart diseases; they were more frequent in women and they increase with the age, being the over 75 years-old and the 65-74 y groups the most affected (31,4
