Revista en Ciencias del Movimiento Humano y Salud , 2009,
Abstract: El propósito del estudio es comparar el gasto energético medio y los niveles de actividad física entre los jóvenes de Monterrey, México y Zaragoza, Espa a; considerando variables como género, tipo de escuela y momento de la semana (jornada escolar o fin de semana). Métodología: estudiantes adolescentes de 12 a 17 a os, pertenecientes a las escuelas públicas y privadas de la ciudad de Monterrey (N= 396) y Zaragoza (N= 394). Se utilizó el cuestionario Four by one-day physical activity questionnaire con una fiabilidad de .89, realizado con un test-retest por su adaptación de formato. Resultados: existe tanto en Zaragoza como en Monterrey un número importante de escolares con bajos niveles de actividad física. Casi la mitad de los escolares se han tipificado como inactivos y muy inactivos. El gasto energético fue muy similar 37.52 kcal/kg/día ± 2.12 para Zaragoza y 37.66 kcal/kg/día ± 2.95 para Monterrey, en las dos ciudades se aladas. Conclusiones: en cuanto al género los hombres presentan mayores niveles de actividad física que las mujeres dato que coincide con la mayoría de los estudios. Los escolares realizan mayor nivel de actividad física durante la jornada escolar que en los fines de semana. Por un lado, obtuvieron un mayor gasto energético los hombres que estudian en las escuelas privadas de Zaragoza y por otro lado, las mujeres de escuelas públicas de Monterrey.

World Journal of Cardiovascular Diseases (WJCD) , 2014, DOI: 10.4236/wjcd.2014.42010
Abstract:

The present study aims to determine the influence of microvascular dysfunction (MVD) in the prognosis of patients presenting isolated left bundle branch block (LBBB). Methods: We studied 30 patients (pts), 22 males, 8 females, mean age 57 ± 4 years, with isolated LBBB, with a mean follow up of 48 ± 6 months. The control group consisted of 20 healthy individuals, 12 males, mean age 52 ± 10 years. Both groups were screened for cardiovascular risk factors (RF); they also had an echocardiogram and Coronary CT Scan, ruling out both structural heart disease and obstructive lesions of the epicardial coronary arteries. A myocardial perfusion study was then performed, with two groups emerging according to these results: Group A, 8 pts (26%), with reversible perfusion defects, in which the diagnosis of MVD was suspected, and Group B, 22 pts (74%), with either normal perfusion or minor septal/apical reversible defects (related to LBBB). All Group A pts, and 9 of the Group B pts, underwent coronary arteriography, with intracoronary acetylcholine and nitroglycerine infusion, thus evaluating vasomotor response as endothelium dependent (acetylcholine) or endothelium independent (nitroglycerine). During follow up, we reviewed functional class, 12 lead ECG and echocardiogram on a yearly basis. Results: All Group A patients had an abnormal acetylcholine response; only three of them had abnormal response to nitroglycerine infusion, suggesting endothelium dependent MVD. Of those in Group B, only one patient had abnormal acetylcholine response. At the end of the follow up period, 3 pts (37%) in Group A, showed functional class decrease vs 5 pts (22%) of

those in Group B. In Group A, a significant increase of End Diastolic Left Ventricle Diameter (EDLVD) was found (51.6 ± 3.6 vs 59.3 ± 6.8 mm; p < 0.05) with significant decrease in LVEF (62 ± 4.8 vs 46% ± 3.7%, p < 0.01); both controls and Group B showed no variation. In neither group major complications (death, heart failure admissions) were found. Conclusion: We confirm the association between MVD and a worse clinical prognosis in isolated LBBB patients. Repeated ischemia and myocardial fibrosis are highlighted as possible physiopathological mechanisms, precluding a

Abstract: Se trata de la presentación de dos casos de acretismo placentario que ocurrieron en el Hospital Territorial Docente de Cárdenas, con menos de 48 horas de transcurridos de uno a otro, con confirmación de Anatomía Patológica y buena evolución de los pacientes y sus recién nacidos. En un caso se efectuó histerectomía subtotal post cesárea abdominal cuya indicación fue: embarazo a término, trabajo de parto, presentación pelviana, presunta placenta previa y cesárea anterior. En otro caso se efectuó histerectomía total post parto vaginal eutócico ante la imposibilidad de extracción manual de la placenta y hemorragia aguda. We present two cases of placenta accreta attended at the Teaching Territorial Hospital of Cardenas, with less than 48 hours of difference, confirmed by Pathologic Anatomy and a good evolution of the patients and their newborns. In one case we made a subtotal hysterectomy after abdominal cesarean indicated as: term pregnancy, labor, pelvic presentation, presumed previous placenta and anterior cesarean. In the other, we made a total hysterectomy after eutocic vaginal delivery because of the impossibility of manually extracting placenta and acute hemorrhage.

Abstract: shigatoxigenic escherichia coli (stes) belongs to the group of diarrhoea producing bacteria, pathology which still constitutes one of the main causes of morbility in children at a world wide level. stes produces one or more shiga toxins (stx1, stx 2 and their variants) which is their main pathogenicity factor, responsible for the intestinal and systemic complications. transmission can occur person-to-person, or through contaminated water or food. its capacity for producing epidemic outbreaks and the seriousness of the enteritis complications are what confers this microorganism great public health importance. this pathogen is not usually detected at clinical laboratories due to its biochemical and clinical similarities with other enterical pathogens, and it necessary to use serological and molecular methods for its definitive identification and characterization. in this paper, we have revised available information regarding pathogenicity, diagnosis and treatment of stes produced infections

Abstract: Introducción: los estudios cienciométricos utilizan indicadores relativos para la caracterización temática de la producción científica, para identificar las principales fortalezas y debilidades de un país en un dominio del conocimiento. Objetivo: hacer la caracterización temática de la producción científica cubana sobre salud indexada en Scopus durante el período 1996-2010, a partir de patrones de especialización temática. Métodos: estudio descriptivo. Se compilaron datos relativos al número total de documentos indexados por Scopus, así como la productividad y la tasa de crecimiento anual. Se calculó el índice de especialización temática de la producción científica. Resultados: el índice de especialización temática de la producción científica cubana sobre salud alcanzó niveles superiores con respecto a la región y el mundo. Los mayores índices de especialización se alcanzaron en dominios temáticos donde, a su vez, Cuba exhibe importantes indicadores de salud. Las investigaciones publicadas en revistas nacionales indexadas por Scopus influyeron de manera decisiva en el índice de especialización de las principales categorías temáticas estudiadas. Conclusiones: las ciencias de la salud de manera general, y particularmente la salud pública, tienen un rol protagónico dentro de la producción científica nacional. Introduction: scientometric studies use relative indicators for the thematic characterization of scientific production, in order to identify the strengths and weaknesses of a country in a knowledge domain. Objective: the use of specialization patterns for the thematic characterization of the Cuban scientific production in health indexed by Scopus during the 1996-2010 period. Methods: descriptive study. The total number of documents covered by Scopus as well as the productivity and the annual growth rate were compiled. The thematic specialization index of the scientific production was estimated. Results: the thematic specialization index of the Cuban scientific production in health achieved higher levels than those of the Latin American region and the world. The highest indexes went to thematic domains where Cuba shows important health indicators. The published research papers in national journals covered by Scopus have a decisive influence on the specialization index of the main studied thematic categories. Conclusions: health sciences in general, and particularly the public health, have a leading role in the Cuban scientific production.
