Journal of Animal and Veterinary Advances , 2012,
Abstract: Multiparous goats (n=183) of undefined genotype (native x traditional dairy breeds) kept on a desert rangeland were used to assess the effect of concurrent pregnancy and lactation, liveweight and lipid reserves at the sternum at mating on reproductive performance. The extended lactation during the dry season, concurrent with pregnancy, was associated with a lower (P<0.01) pregnancy rate (60 vs 92% for lactating and dry does, respectively), prenatal wastage (77 vs 4%) and kidding rate (14 vs 88%). Body weight at mating, middle of gestation and parturition, as well as sternum width and skin thickness at the sternum region was not different between dry and lactating does. In a second analysis considering only the dry does, the proportion of does pregnant, as well as kidding rates were not affected by body weight of does at mating, middle of gestation and at parturition. However, mean litter size tended to be higher (P= 0.09) for heavier does at mating (1.65 ? 0.48 vs 1.46 ? 0.51) and at the middle (1.65 ? 0.48 vs 1.45 ? 0.51) of gestation. Mean litter weight also tended to be higher (P= 0.06) for heavier does at the middle of gestation (5.40 ? 0.83 vs 4.89 ? 0.87). Body energy reserves, as reflected in sternum width and skin thickness in the sternum region, tended to be related to kidding rates, with does with higher fat reserves supporting higher kidding rates (94 vs 83%; P<0.01). Litter size and weight did not differ among does with different body fat reserves. These data indicate that, although lactation concurrent with gestation in the dry season was not associated with a major weight loss, it had a drastic cost on reproductive effort. Moreover, mean litter size and weight tended to be positively influenced by body weight at mating but not by levels of sternum energy reserves of does.

Abstract: Introducción: El aumento de la población de personas mayores de 65 a os hace cada vez más frecuente su ingreso en los hospitales. El tiempo de estancia hospitalaria de los ancianos suele ser más prolongado que el del resto de pacientes. Objetivo: Analizar la capacidad de prestación de cuidados de 3 unidades de hospitalización de un hospital público y compararla con la demanda de cuidados de los ancianos. Métodos: Estudio prospectivo observacional en 3 unidades de hospitalización de medicina interna de un hospital universitario de la red pública de Andalucía (Espa a). Se ha incluido una muestra de 190 pacientes ancianos hospitalizados. Las variables recogidas fueron: demográficas, relacionadas con la hospitalización, demanda de cuidados y capacidad de prestación de cuidados de la plantilla de enfermería. Los datos se han obtenido del sistema de información del hospital, del conjunto mínimo básico de datos de pacientes y por observación directa mediante el método de nivel de cuidados (MNC). Resultados: La edad media de los ancianos hospitalizados fue de 77,4 a os, con 21,1% de mayores de 85 a os. La estancia media fue de 15,68 días. La estimación de la capacidad de prestación de cuidados de la plantilla de enfermería fue de 2,8 horas/paciente/día (con un índice de enfermeras tituladas del 60%). A partir de la medición de niveles de dependencia, la demanda de cuidados media de los ancianos fue de 4,9 horas/paciente/día. Esta diferencia supone un déficit anual de 51 profesionales de enfermería en la plantilla de las 3 unidades de hospitalización. Los factores que influyen en la demanda de cuidados de los ancianos son la edad, días de estancia hospitalaria, el diagnóstico médico y el destino del paciente al alta. También se encuentra una relación con la presencia de un familiar acompa ando al paciente (cuidador familiar). Los cuidados básicos representan un 65,7% del total de cuidados requeridos. Conclusiones: La proporción de ancianos frágiles ingresados en los hospitales está en aumento. La demanda de cuidados de los ancianos es mayor que la capacidad de provisión de la plantilla de enfermería del hospital, lo cual genera un déficit que tiene que ser asumido por los cuidadores familiares. Introduction: The increase in the elders’ population makes more and more frequent its admittance in hospitals. The hospital stay of the elder patients is usually longer than the rest of patients. Aim: To analyze the care delivery capacity in 3 units of the hospital and to compare it with the needs for care of the elders. Methods: Observational and prospective study in 3 In

Abstract: shrubs usually have a beneficial effect on herb species richness. in this study, the importance of shrubs/small trees on herb species richness and abundance in the prepuna biogeographical region was evaluated at the patch (individual patches and all individual patches considered together, i.e., patch types), community (landscape) and regional levels. at individual patch level, a tendency towards more herb species in association with shrub undercanopies was found, although only in two of the four localities studied the differences were statistically significant. at patch type level, more species were found associated to the below shrub microhabitats in all four localities. the analyses conducted with rarefaction runs confirmed a greater species number beneath shrubs and showed the positive effect of the shrubs on species richness at community scale, although showing variations in magnitude in the different localities. the patterns found were consistent across the latitudinal gradient studied, indicating that, at least in certain years, the positive influence of shrubs on herbs is not only a local phenomenon. moreover, as shrubs harbor different herb communities depending on locality, their positive effect seems to increase at regional scales. this study is the first reporting the beneficial role of shrubs on herb richness in the subtropical andes.

Abstract: la hipertensión es un factor de riesgo cardiovascular muy prevalente en el mundo, y especialmente abrumador en los países de bajos y medianos ingresos. informes recientes de la oms y del banco mundial destacan la importancia de las enfermedades crónicas tales como la hipertensión, como obstáculo al logro de un buen estado de salud. se debe agregar que, para la mayoría de los países de bajos y medianos ingresos, estrategias deficientes de la atención primaria de la salud son obstáculos mayores par el logro del control de la presión arterial. es más, la epidemiología de la hipertensión y enfermedades relacionadas, los recursos y las prioridades de salud, el estado socioeconómico de la población, varían considerablemente en diferentes países y en diferentes regiones de países individuales. teniendo en cuenta las bajas tasas de control de la presión arterial logrados en latinoamérica y los beneficios que se puede esperar de un mejor control, se decidió invitar a especialistas de diferentes países latinoamericanos a analizar la situación de la región y redactar un documento de consenso sobre la detección, evaluación y tratamiento de la hipertensión que podría ser adecuado del punto de vista costo-utilidad. las recomendaciones incluidas aquí son el resultado de documentos preparatorios escritos por expertos invitados y el muy activo debate posterior en diferentes paneles de discusión, realizados durante dos días en asunción, paraguay en mayo del a?o 2008. por último, para mejorar la práctica clínica, la publicación de estas pautas debe ser seguida por la implementación de intervenciones efectivas capaces de vencer las barreras (cognitivas, de comportamiento y afectivas) que previenen los cambios de actitud tanto en médicos como en pacientes.

Abstract: La miastenia gravis es una entidad clínica de origen autoinmune, cuya terapia habitual se realiza con drogas anticolinérgicas, la timectomía o la terapia con esteroides. Fue el objetivo del trabajo el conocer los cambios que se producen en el tama o del área tímica, con el uso de esteroides, en una paciente de 2 a os de edad, que presentaba miastenia gravis juvenil, con una hiperplasia tímica. Esta glándula alcanzó un área máxima de 1 928 mm. Con el uso de la prednisona a 60 mg por semanas se produjo una timectomía medicamentosa, con la reducción del área tímica a 439 mm y remisión total de la sintomatología. Se realizaron las mediciones periódicamente durante un a o de los cambios del área de este órgano. No se produjeron recaídas de la enfermedad de base. La ultrasonografía demostró ser un método útil, por ser rápido, barato y no invasiva y permite un ajuste adecuado de la dosis de esteroides que se administrará. Myasthenia gravis is a clinical agent of autoimmune origin, whose habitual therapy includes anticholinergic drugs, thymectomy, or therapy with steroids. The objective of this paper was to know the changes that occur in the size of the thymic area in a 2-year-old patient with juvenile myasthenia gravis and with thymic hyperplasia. This gland reached a maximum area of 1 928 mm and with the use of 60 mg of prednisone per week a medicamentosus thymectomy was performed with the reduction of the thymic area to 439 mm and total remission of the symptomatology. The changes of the area of this organ were periodically measured during a year. There were no relapses of the base disease. The ultrasonography proved to be a useful method, since it is fast, cheap and noninvasive and allows an adequate control of the steroids dose to be administered.

Abstract: ngenital malformations in Ecuadorian children: urgent need to create a National Registry of Birth Defects Original Research (23200) Total Article Views Authors: Fabricio González-Andrade, Ramiro López-Pulles Published Date April 2010 Volume 2010:3 Pages 29 - 39 DOI: http://dx.doi.org/10.2147/TACG.S8794 Fabricio González-Andrade1, Ramiro López-Pulles2 1Department of Medicine, Metropolitan Hospital, Quito, Ecuador; 2Science and Technology Process of the Ministry of Public Health, Biomedical Center of the Central University and Regional Autonomic University of the Audes, Quito, Ecuador Universidad Central del Ecuador, Quito, Ecuador Aim: This study sets out (a) to estimate the prevalence of admissions by birth defects, using the official database of hospitals of Ecuador; and (b) to set the basis for a new National Register of Birth Defects in Ecuador that works as a program for the clinical and epidemiological investigation of risk factors in the etiology of congenital anomalies in Ecuadorian hospitals, using a case-control methodological approach. This is the first report in their class. Methods: The data used in this study are derived from the National Register of Hospital Admission/Discharges of the Instituto Nacional de Estadísticas y Censos; data of the Ministry of Public Health were also used. Ecuador does not have an official Medical Birth Registry or a Congenital Malformations Registry. Results: A total of 51,375 discharges by congenital malformations were registered in a 7-year period. Of these, 16,679 admissions were of children aged less than 1 year of age, with a birth prevalence rate (BPR) of 72.33/10,000 births. 77% of the congenital defects registered comprise the 50 most common birth defects observed in this age group. Cleft lip was the most prevalent birth defect in children less than 1 year of age and the second most common defect in children 1 to 5 years of age. Unilateral cleft lip shows a BPR of 4.57/10,000 births; cardiac birth defects as a group have a BPR of 4.2; hydrocephalus a BPR of 3.77; and Down’s syndrome a BPR of 3.70. Undescended testicle was the most prevalent birth defect in children between 1 to 5 years. 9384 children under 1 year of age were male (55.9%) and 7053 were female (42.1%). BPR in males was 40.45 and in females 30.40. Conclusion: This report documents the prevalence estimates for birth defects reported in the hospital discharge data. These estimates are important to 1) plan for health-care and education needs of the Ecuadorian population, 2) identify increased occurrences of birth defects in specific geographic regions, 3) serve as a reference point for assessment of provincial surveillance systems, 4) evaluate national public health interventions, 5) compare Ecuador prevalence estimates with those of other countries, and 6) help determine the appropriate allocation of resources for basic and public health research. There is an urgent need to establish a National Registry of Birth Defects involving diffe
