Anemia y fragilidad en adultos mayores hospitalizados en el servicio de geriatría del Hospital Nacional Alberto Sabogal Sologuren - 2023
No full textEl objetivo de la investigación es determinar la relación entre anemia y fragilidad en adultos mayores hospitalizados en el servicio de geriatría del Hospital Nacional Alberto Sabogal Sologuren del año 2023. La fragilidad se convierte en una carga emergente para la salud pública mundial, con el rápido crecimiento de la población mundial que envejece y está relacionada con eventos adversos de la salud; aumento de la mortalidad, hospitalización, caídas y fracturas, el deterioro cognitivo, la discapacidad y el ingreso a cuidados de largo plazo. Asimismo, la hemoglobina baja refleja una disminución de la función fisiológica, incluida una disminución de la respuesta inmune, desnutrición y baja resistencia a la invasión externa. Sin embargo, los mecanismos específicos que justifican la asociación de la anemia con eventos adversos de salud en esta población son todavía desconocidos. Los resultados de esta investigación permitirán emplear políticas efectivas, detección temprana e intervenciones de salud. Los profesionales de la salud que atienden a adultos mayores se enfocarán en el cribado, la evaluación de las causas y el tratamiento de la anemia como método para evitar, retrasar o incluso revertir la fragilidad, justificándose el reconocimiento, la evaluación y el tratamiento de la anemia entre esta población vulnerableSubmitted by Mónica Barrueto ([email protected]) on 2024-08-09T15:02:06Z

Complexity Analysis of Spontaneous Brain Activity in Attention-Deficit/Hyperactivity Disorder: Diagnostic Implications
No full textBackground: Attention-deficit/hyperactivity disorder (ADHD) is defined as the most common neurobehavioral disorder of childhood, but an objective diagnostic test is not available yet to date. Neurophychological, neuroimaging, and neurophysiological research offer ample evidence of brain and behavioral dysfunctions in ADHD, but these findings have not been useful as a diagnostic test.Methods: Whole-head magnetoencephalographic recordings were obtained from 14 diagnosed ADHD patients and 14 healthy children during resting conditions. Lempel-Ziv complexity(LZC) values were obtained for each channel and child and averaged in five sensor groups: anterior, central, left lateral, right lateral, and posterior.Results: Lempel-Ziv complexity scores were significantly higher in control subjects, with the maximum value in anterior region. Combining age and anterior complexity values allowed the correct classification of ADHD patients and control subjects with a 93% sensitivity and 79% specificity. Control subjects showed an age-related monotonic increase of LZC scores in all sensor groups, while children with ADHD exhibited a nonsignificant tendency toward decreased LZC scores. The age-related divergence resulted in a 100% specificity in children older than 9 years.Conclusions: Results support the role of a frontal hypoactivity in the diagnosis of ADHD. Moreover, the age-related divergence of complexity scores between ADHD patients and control subjects might reflect distinctive developmental trajectories. This interpretation of our results is in agreement with recent investigations reporting a delay of cortical maturation in the prefrontal cortex.</p

Thypa subulata Crespo & Perez Mor
No full textEn este capítulo se proporciona información sobre aspectos biológicos, tales como los factores que influyen sobre la germinación de semillas, la fenología, el crecimiento y el desarrollo, y aspectos de control de Typha subulata (Totora), planta nativa de América, herbácea, perenne que se propaga a través desemillas y rizomas. Crece tanto en sistemas de aguas quietas como en movimiento. Typha es especialmente un problema en cultivos de arroz y puede invadir canales de irrigación y drenaje impidiendo elfl ujo de agua. Esto se traduce en dificultades de manejo de las operaciones de riego asociadas con lamedición de caudales, inundación u operatividad de los desagües, aumento de la sedimentación, incrementode las pérdidas de agua por evaporación y además obstaculización de las actividades recreativas tales como pesca, la natación y la navegación.Thypa subulata (Totora), is a perennial herbaceous species which propagate through seed and rhizomes and is native to America. In this chapter information is provided on some of its biological aspects, such as the factors that influence seed germination, phenology, growth and development. Information on its control is also included. This species can grow in either still or running waters. It is problem in rice crops and in irrigation and drainage channels where it can prevent normal water flux. Watering operations may be affected with consequences on flow measurements and the operation of drainage systems due to an increased sedimentation and water loss through evaporation. The invasion by this species also hinders recreational activities such as fishing, swimming and navigation.Fil: Sobrero, Maria Teresa. Universidad Nacional de Santiago del Estero.

Costs and benefits of debt and debt service reduction
No full textThe author evaluates the costs and benefits of debt and debt service reduction (DDSR) from the point of view of five countries that have concluded Brady deals: Costa Rica, Mexico, the Philippines, Uruguay, and Venezuela. He concludes that, contrary to widely held views, commercial banks have probably benefited from the operations. Commercial bank participation in DDSR is voluntary, so direct financial savings to the country are probably negative at present values. The benefit from DDSR is not that debt is bought at"bargain prices"at the expense of commercial banks. It appears difficult to justify a DDSR operation on purely financial grounds. A more realistic way to look at a DDSR operation is to view it as a"project"that involves a certain financial cost. The return on such a project is how the DDSR operation improves the macroeconomy, or contributes to development. The main purpose of DDSR is to establish a more efficient arrangement between debtor countries and commercial banks, leading to improved conditions for development. A DDSR operation that does not help development is costly and should not be undertaken. The impact of DDSR on development is usually measured by the increase in the growth rate of GDP, but it is too soon to measure that for these five countries. A suitable alternative is to look at the change in investment patterns. A strong policy framework is needed if debt and debt service reduction are to significantly improve development. In Mexico and, to a lesser extent, Venezuela, improved and sustained strong adjustment policies have generated the greatest development benefits. Gains have been less in smaller countries where policies were not as supportive. The author concludes that for a country to benefit from DDSR, it needs significant indirect benefits (such as increased domestic and foreign savings). Direct benefits are likely to be negative because of the commercial banks'financial gains and because DDSR operations are frontloaded. DDSR operations cannot be justified solely by direct benefits and savings in cash flow.Strategic Debt Management,Banks&Banking Reform,Economic Theory&Research,Environmental Economics&Policies,Financial Intermediation
Stuckenia striata (Ruiz & Pav.) Holub
No full textStuckenia striata (Ruiz & Pav.) Holub (Potamogeton pectinatus L. var striata) es una planta monocotiledónea acuática vascular arraigada de amplia adaptación a sistemas lénticos y loticos. Originaria de sur América, es conocida como "lama". Su hábito de crecimiento es perenne y siempre verde, con tallos ramificados cerca de superficie del agua y hojas lineales con una cutícula impermeable. El sistema subterráneo está compuesto por raíces, rizomas y tubérculos. Mientras que la reproducción sexual a través de semillas suministra largo tiempo de perennación y elevada distancia de dispersión, la reproducción asexual a través de rizomas y tubérculos proporciona lo contrario. La amplia plasticidad fenotípica le permite adaptarse a muchos ambientes acuáticos estableciéndose en 18 provincias de la Argentina. S. striata, que puede alcanzar 2,7 m de altura, tiene tolerancia a crecer a bajos niveles de luz, está adaptada al disturbio y niveles intermedios de salinidad de agua. Como malezas produce el bloqueo de canales de riego y drenaje que se traduce en una reducción de agua a los regantes y en un aumento de salinización de los suelos. Dificulta la recreación en lagos y lagunas interfiriendo con la navegación, natación y pesca. Para su control se utilizan medios físicos, mecánicos, biológicos y químicos.Stuckenia pectinata (Ruiz y Pav.) Holub (Potamogeton pectinaturs L. var. striata (Ruiz y Pav.) Hagstr.) is an aquatic monocotyledonous perennial evergreen species, that grows fixed to the soil, and has a broad distribution in lotic and lectic aquatic systems of Argentina. Its stems may reach up to almost three meters length with dense ramifications, generating at the water level a dense canopy of linear leaves with an impermeable cuticle. Its ability to reproduce sexually by seeds provides the potential for an extensive dispersion in the colonized aquatic systems, while its underground system represented by rhizomes and tubers contributes to its local existence. Due to its vast phenotipic plasticity in association with its tolerance to low levels of light, disturbation, and intermediate levels of water salinity, it can adapt very well to a diversity of aquatic environments. As a weed, it represents a serious problem in irrigation systems, causing the obstruction to the transport of water in the drainage channels, which in turn causes the salinization of the neighboring soils. In other systems used for recreational purposes, it can cause problems by interfering with navigation and fishing. Physical, mechanical, biological and chemical methods are all employed as strategies for the control of this species.Fil: Bentivegna, Diego Javier.
