Deflazacort Versus Prednisolone: Randomized Controlled Trial in Treatment of Children With Idiopathic Nephrotic Syndrome

Background: Corticosteroids are the main therapy of nephrotic syndrome and goal of corticosteroid therapy is to obtain maximum clinical benefit with minimum adverse effects. Children are more vulnerable to side effects of corticosteroids related to growth and adrenal suppression, so a search for an alternative steroid with fewer side-effects is underway. Deflazacort is an oxazoline derivative and preliminary data suggest reduced osteoporosis, lesser growth retardation and weight gain with deflazacort. Objectives: This study was done to compare the effectiveness and safety of deflazacort in idiopathic nephrotic syndrome. Patients and Methods: Twenty five children with age between 2 to 12 years, with idiopathic nephrotic syndrome were enrolled. They were randomly assigned to receive deflazacort (Group A, n = 12) or prednisolone (Group B, n = 13) and were followed up for six months. Results: All children of group A and 11 of group B had remission. Two children from group B were steroid resistant. Mean time taken to induce remission was significantly (P = 0.012) less in group A (10.25 ± 2.41 days) than group B (12.55 ± 1.44 days). One patient in group A had relapse on follow up as compared to 3 in group B (P = 0.58). Statistically significant difference (P = 0.03) in change in mean height was found between group A (2.13 ± 0.50cm) and B (1.44 ± 0.45 cm), with group B gaining less height. Conclusions: Remission rate in both groups was comparable although time taken to induce remission was shorter in deflazacort group and there was a significant difference in change of mean height on follow up with prednisolone group gaining lesser height.

Faecal bacteria in Perna perna (Linnaeus, 1758) (Mollusca: Bivalvia) for biomonitoring coastal waters and seafood quality

O desenvolvimento urbano em áreas costeiras é intenso e o aumento das descargas de esgoto é uma das conseqüências. Assim, leis específicas que regulem limites para a contaminação microbiológica das águas e de alimentos de origem marinha são necessárias. O objetivo deste estudo é avaliar a utilização de Enterococos e coliformes termotolerantes na carne de mexilhões Perna perna como alternativa para o monitoramento da qualidade microbiológica de águas costeiras. O estudo também considera relações alométricas aplicadas às taxas de clearance para entender a concentração de bactérias pelo molusco. As densidades bacterianas obtidas no molusco foram de 50 a 4300 vezes maiores do que nas amostras de água coletadas próximas dos moluscos e alguns foram considerados impróprios para consumo, mesmo quando as águas não mostraram restrições. A taxa de clearance média obtida para retenção de Enterococos foi 317.7 ml h-1 e essas taxas (CR) puderam ser relacionadas com o tamanho dos mexilhões (L) pela equação CR = 28.3229L1.6421. Os resultados mostram que as densidades bacterianas nos tecidos dos mexilhões podem refletir a contaminação crônica do ambiente e que as taxas de clearance devem ser consideradas para a tomada de decisão em situações onde, por exemplo, se deseja implantar mexilhões para cultivo.

Entre o cartão-postal e a cidade real: um estudo sobre paisagem e produção imobiliária em Natal/RN

Recent studies concerning the landscape have investigated the most important activities that contribute for its modification and have tried to better understand the society through the marks left by its quotidian. It is understood that singular landscapes constitute the cultural patrimonies of the cities, once they are part of the daily life of the citizens and are present in their social representations. Some contemporary authors defend the preservation of the natural and urban landscape trying, specially, to keep its importance for the local population. Natal is a city where the ambient qualities are well defined and known by the beauty of the area where it is located. Situated just between a river and the sea, the city grew following its geographic characteristics. The Potengi River, the Atlantic Ocean and the vast dunes ecosystem represented natural limits to the urban expansion; at the same time they have favored the development of a landscape pattern marked by the dialectic between the natural elements and the human interventions. However, this relationship changed after the intensification of the high rising development process that took place since the 1960s. The urban legislation tried to preserve the features of the local landscape delimiting Areas for Controlling Building High , destined to protect the scenic value of some parts of the city. On the other hand, the civil construction sector has made constant pressure in sense to abolish or to modify this legal instrument, aiming profits that have increased, in the 1990s, because of the consumption and the qualification of the urban space for tourist activities. It is necessary the raising of new elements to stimulate the quarrel about the landscape preservation, the process of the urban space production and the best way for the legislation implementation. This work tries to raise elements about the subject at local level, in sense to use Natal City experience to contribute for the formulation of indicators to raise the question about the lack of measure for subjective values, for example the cultural and affective value of the landscape. The natural elements inserted in the urban profile, represent strong visual references and supply identity to the town; they are part of the collective imaginary and are detached in the social context of the city. Then, why the preservation of the landscape, that estimates the improvement in the quality of life, is not enough to justify the controlling building high already previewed as part of Natal City Legislation? These questions send us to the approach of the landscape, as a community patrimony, alerting that some of its significant esthetics attributes must be preserved as a legacy for the future generations

Agricultural R&D indicators factsheet: Brazil.

Brazil's agricultural research system is by far the region's largest, in terms of both research capacity and spending. Almost half of all agricultural researchers are employed by the main federal government agency, Embrapa, and a further quarter are employed by the state agricultural research organizations (OEPAS). During 2006-2013, agricultural R&D spending rose by 43 percent due to growth at Embrapa and in the higher education sector, particularly among federal universities. At 1.82 percent, spending as a share of AgGDP is the highest in Latin America.

Influência da profundidade e dos parâmetros ambientais sobre o desenvolvimento de Gracilaria birdiae (Rhodophyta, Gracilariales) em viveiro de camarão

This study evaluates the influence of depth and environmental parameters on the development of Gracilaria birdiae Plastino & Oliveira (Gracilariaceae Rhodophyta) in an organic shrimp pound (Litopenaeus vannamei) under euthrophical conditions. PVC structures (module) witch four ropes laden with 150 g of macroalgae each, were kept during 35 days at three different depths (surface, 10 and 20 cm depth). Wet biomass weighing and environmental parameters (temperature, salinity, turbidity, pH, transparence, precipitation, evaporation, insolation, accumulated solar radiation, nitrite, nitrate, ammonium and orthophosphate) were measured weekly. At all three proposed depths, the macroalgae displayed a higher biomass at the end of experiment than at the initial inoculations. The module kept at a 10 cm depth presented the greatest average biomass (186,3), followed by that kept at 20 cm (180,4 g) and the surface module (169,9 g). Biomass variations showed algae to suffer the direct effects of depths. Biomass loss was associated with the factors that influence light penetration, such as sediment deposits above the thallus, rate of evaporation and precipitation. The smallest loses occurred in the algae kept on surface (0,16%), followed by the algae kept at 20 cm (0,20%) and 10 cm (0,22%). The specific growth rate (SGR) of G. birdiae showed no significant difference between the three depths nor the sample periods. Nevertheless, the modules kept at 10 and 20 cm depths presented similar growth evolution, both growing 0,38%·per day-1, while the module kept on surface had an average SGR of 0,36%·day-1. The models related to growth rate demonstrated temperature, salinity, pH, orthophosphate, ammonium, precipitation and turbidity as the principal environmental parameters influencing the development of G. birdiae

Projeto, construção e análise de um prototipo vibracional em escala de bancada aplicável ao tratamento de água de produção de petróleo bruto, mediante inovadora operação híbrida de adsorção e auto-flotação

A self-flotator vibrational prototype electromechanical drive for treatment of oil and water emulsion or like emulsion is presented and evaluated. Oil production and refining to obtain derivatives is carried out under arrangements technically referred to as on-shore and off-shore, ie, on the continent and in the sea. In Brazil 80 % of the petroleum production is taken at sea and area of deployment and it cost scale are worrisome. It is associated, oily water production on a large scale, carrier 95% of the potential pollutant of activity whose final destination is the environment medium, terrestrial or maritime. Although diversified set of techniques and water treatment systems are in use or research, we propose an innovative system that operates in a sustainable way without chemical additives, for the good of the ecosystem. Labyrinth adsor-bent is used in metal spirals, and laboratory scale flow. Equipment and process patents are claimed. Treatments were performed at different flow rates and bands often monitored with control systems, some built, other bought for this purpose. Measurements of the levels of oil and grease (OGC) of efluents treaty remained within the range of legal framework under test conditions. Adsorbents were weighed before and after treatment for obtaining oil impregna-tion, the performance goal of vibratory action and treatment as a whole. Treatment technolo-gies in course are referenced, to compare performance, qualitatively and quantitatively. The vibration energy consumption is faced with and without conventional flotation and self-flotation. There are good prospects for the proposed, especially in reducing the residence time, by capillary action system. The impregnation dimensionless parameter was created and confronted with consecrated dimensionless parameters, on the vibrational version, such as Weber number and Froude number in quadratic form, referred to as vibrational criticality. Re-sults suggest limits to the vibration intensity

The mythical properties of police body-worn cameras: A solution in the search of a problem

Over the past few years, Australian police agencies have begun to enthusiastically introduce body-worn cameras on police personnel. These devices are now either implemented or under trial across the country. There is also an emergent ‘surveillance consensus’ (Hempel and Töpfer 2009) concerning their use amongst Australian police. While more detailed empirical examination of information flows that shape this surveillance consensus is warranted, this contribution to the debate seeks to draw from policing scholarship to critically explore the intersections between the rationalizations for body-worn cameras and the broader policing scholarship. More directly, body-worn cameras cannot be understood in narrow instrumental terms, but must be located within the broader literature on governing police and the law and order politics that surrounds many contemporary police and criminal justice reforms (Cox 2015; Gregg and Wilson 2015). I begin with a summary of the introduction of body-worn cameras in Australia. The article then identifies five problems body-worn cameras purportedly address and provides a brief case summary indicating how current ‘privacy protections’ fail to establish real limits to the collection, use, and dissemination of images from body-worn cameras.

Teaching an old game new tricks : long-term feedback on a re-designed online role play

Despite an extensive history of use in teaching Political Science subjects, long-term scholarly studies of online role plays are uncommon. This paper redresses that balance by presenting five years of data on the Middle East Politics Simulation. This online role play has been run since the 1990s and underwent significant technical upgrade in 2013-14. The data presented here covers student feedback to this upgrade process and the factors that can influence their response. Key indications are that students tend to recognise when something is fit (or not) for its purpose and will forgo attractive and well-appointed online environments if the underlying learning exercise is valued. However, there are limits to this minimalism and whilst designers do not need to replicate every Internet trend, attention needs to be paid to broader changes in technology, such as access platform and changing avenues of political communication. The study demonstrates that long-term monitoring of online role play exercises is important to allow informed changes to be implemented and their impacts properly assessed.

Decomposition of temporal changes in construction labour productivity

Construction productivity is recognized as an indicator reflecting the performance efficiency and competitiveness of the industry. A large amount of research has been carried out focusing on the decomposition of the influential factors and the temporal trends of construction productivity changes, respectively. However, the decomposition of the temporal changes in construction labour productivity has not yet been explored. Analogous to the framework of the productivity frontier, this research argues for a four-component decomposition of the temporal changes in construction labour productivity, including technology, technology-utilization efficiency, the capital-labour ratio and production capacity. An error correction model is subsequently estimated using the panel data regression method to investigate the effects of these components on the temporal changes in construction productivity across a sample of the Australian construction industry. The empirical results con?rm that the effects of the four components on the temporal changes in construction productivity changes vary over the observed time periods. From the aggregate level, the technology-utilization efficiency and capital-labour ratio across the regions are found to be barriers to growth in Australian construction productivity. Nevertheless, the effects of technology-utilization efficiency and production capacity varied significantly over the three sub-periods, when innovative national economic systems were introduced.

Caracterización nutricional mediante antropometría de los niños sanos menores de 5 años asistentes a una institución de salud en Puerto Inírida 2014

Introducción: Siendo la desnutrición infantil, un indicador trazador en el perfil de salud de una población y prioridad establecida por los objetivos de desarrollo del milenio y el plan decenal de salud pública en Colombia - PDSP en su dimensión de seguridad alimentaria y nutricional, mantiene gran prevalencia a nivel nacional a pesar de presentar subregistro en la información reportada, por ende, es prioridad la medición, notificación y tratamiento de la misma. La OMS estandarizó los parámetros de medición y el gobierno nacional los adoptó mediante la resolución 2121 de 2010. Sin embargo, para disminuir el indicador de desnutrición que al año 2015 debería estar reducido en un 50% según el PDSP, es necesario identificar el sub registro que hay en el diagnóstico de la misma. Metodología: Se realizó un estudio poblacional, descriptivo y transversal, en el cual se analizó la base de datos de los niños menores de 5 años asistentes a consulta de crecimiento y desarrollo en una institución de salud del municipio de Puerto Inírida, con el fin de realizar una caracterización nutricional basados en mediciones antropométricas y contrastándolas realizadas por los profesionales de salud con las encontradas utilizando los patrones establecidos por la OMS. La información se analizó con el Software WHO Anthro propiedad de la OMS. Resultados: Se encontró que el 33,6% de los menores de 5 años registrados presentan desnutrición crónica, el 7,6% desnutrición aguda, el 13,2% de desnutrición global y el 13,9% tiene obesidad. Al discriminarlo por edad se encontró mayor prevalencia de desnutrición crónica en ambos sexos, siendo mayor en población de sexo masculino (40,1% masculino – 27,6% femenino); al igual que al realizar la comparación por pertenencia puesto que se encuentra la misma prevalencia en desnutrición crónica (29,1% en población indígena y 29% en población no indígena). Según los estándares de la OMS, en la población estudiada 12 se identificaron 243 casos de malnutrición, mientras que en la consulta de crecimiento y desarrollo fueron diagnosticados como casos de malnutrición por los profesionales de salud solo 99. Discusión: La malnutrición es un problema estructural, por ende, se deben tener en cuenta factores tanto intrínsecos como extrínsecos de la persona. Las medidas antropométricas son sólo una manera de medir, que se debe contextualizar con el entorno y las condiciones socioeconómicas, patológicas y culturales en las que se encuentre la población. El estado nutricional de los menores asistentes a los controles de crecimiento y desarrollo de la población estudiada, se encuentra mal registrado, de la misma manera se encontró una gran prevalencia de desnutrición crónica que es un determinante en la calidad de vida. Es imperante la implementación de políticas públicas adecuadas que permitan profundizar en las causas de este flagelo y así mismo en su tratamiento.

Diversity of new root nodule bacteria from Erythrina velutina Willd., a native legume from the Caatinga dry forest (Northeastern Brazil).

This study aims to evaluate the phenotypical characteristics of bacterial isolates from mulungu (Erythrina velutina Willd.) nodules and determinate their Box-PCR fingerprinting. All bacteria were evaluated by the following phenotypic characteristics: growth rate, pH change, colony color and mucus production. The bacterial isolates able to re-nodulate the original host were also evaluated regarding its tolerance to increased salinity and different incubation temperatures, ability to growth using different carbon sources, intrinsic antibiotic resistance and ?in vitro? auxin biosynthesis. The molecular fingerprints were set up using the Box-PCR technique and the isolates were clustered by their profiles. Among the 22 bacterial isolates obtained, eight were able to re-nodulate the original host. Among the nodule inducing isolates, some were tolerant to 1% of NaCl and 39° C and all of them metabolized the maltose, fructose, glucose, sucrose and arabinose, were resistant to rifampicin and produced auxin. The bacteria showed low genetic similarity among them and reference strains, which indicates the great genetic variability of the isolates. The results of this work are the first reports about the bacterial isolates able to nodulate this species. A more deep study of these bacteria may reveal the existence of isolates tolerant to environmental stresses and suitable as a future mulungu inoculant.

Public debt and the limits of fiscal policy to increase economic growth

Research that seeks to estimate the effects of fiscal policies on economic growth has ignored the role of public debt in this relationship. This study proposes a theoretical model of endogenous growth, which demonstrates that the level of the public debt-to-gross domestic product (GDP) ratio should negatively impact the effect of fiscal policy on growth. This occurs because government indebtedness extracts part of the savings of the young to pay interest on the debts of the older generation, who are no longer saving. Therefore, the payment of debt interest assumes an allocation exchange role between generations that is similar to a pay-as-you-go pension system, which results in changes in the savings rate of the economy. The major conclusions of the theoretical model were tested using an econometric model to provide evidence for the validity of this conclusion. Our empirical analysis controls for timeinvariant, country-specific heterogeneity in the growth rates. We also address endogeneity issues and allow for heterogeneity across countries in the model parameters and for cross-sectional dependence.

Assessing population limits : a carrying capacity approach to planning

While purporting to enhance Australia’s sustainability, the federal government’s Population Strategy rejects the assessment of the limiting factors to future population growth, thus avoiding urgent threshold issues such as resource depletion and environmental destruction. A more forward-thinking and whole-system perspective would assess and incorporate critical biophysical limits into governance processes with suitable prioritisation. It would encourage communities to examine their individual and collective responsibilities in the context of these limits in order to most equitably optimise outcomes; and it would employ both a resource-based examination of minimum population requirements, and an impact-based assessment of maximum thresholds. This carrying capacity approach to planning could help guide society towards a more sustainable future.

Age and size composition, growth rate, reproductive biology, and habitats of the West Australian dhufish (Glaucosoma hebraicum) and their relevance to the management of this species

Samples of the commercially and recreationally important West Australian dhufish (Glaucosoma hebraicum) were obtained from the lower west coast of Australia by a variety of methods. Fish <300 mm TL were caught over flat, hard substrata and low-lying limestone reefs, whereas larger fish were caught over larger limestone and coral reef formations. Maximum total lengths, weights, and ages were 981 mm, 15.3 kg, and 39 years, respectively, for females and 1120 mm, 23.2 kg, and 41 years, respectively, for males. The von Bertalanffy growth curves for females and males were significantly different. The values for L∞, k, and t0 in the von Bertalanffy growth equations were 929 mm, 0.111/year, and –0.141 years, respectively, for females, and 1025 mm, 0.111/year, and –0.052 years, respectively, for males. Preliminary estimates of total mortality indicated that G. hebraicum is now subjected to a level of fishing pressure that must be of concern to fishery managers. Glaucosoma hebraicum, which spawns between November and April and predominantly between December and March, breeds at a wide range of depths and is a multiple spawner. The L50’s for females and males at first maturity, i.e. 301 and 320 mm, respectively, were attained by about the end of the third year of life and are well below the minimum legal length (MLL) of 500 mm. Because females and males did not reach the MLL until the end of their seventh and sixth years of life, respectively, they would have had, on average, the opportunity of spawning during four and three spawning seasons, respectively, before they reached the MLL. However, because G. hebraicum caught in water depths >40 m typically die upon release, a MLL is of limited use for conserving this species. Alternative approaches, such as restricting fishing activity in highly fished areas, reducing daily bag limits for recreational fishermen, introducing quotas or revising specific details of certain commercial hand-line licences (or doing both) are more likely to provide effective conservation measures.
