The relationship between poverty and social determinants of growth in low-income Brazilian children
No full textStunting affects 159 million children under the age of five, while 41 million children are overweight. In general, poorer nutritional and health outcomes are associated with poverty. Poverty has several dimensions and can be defined in several ways, not only as monetary (income) poverty, and sociodemographic characteristics should also be taken into consideration when investigating the influence of poverty on health and nutrition of individuals. The objective of this dissertation was to determine how social and parental characteristics influence nutritional status of children relative to (income) poverty, using longitudinal data from about nutrition education intervention conducted with 500 low-income Brazilian children followed from birth to 7 years. Children living below the poverty line (BPL) had higher prevalence of stunting at 7y compared to children living above the poverty line (APL). Prevalence of overweight did not differ between groups. BPL was associated with increased odds of short exclusive breastfeeding, and participation in a nutritional intervention did not reduce the gap between infants ABL or BPL, indicating poorer children continue to be more vulnerable. More than income, living conditions of poor families could have been associated with the poorer nutritional outcomes of the BPL. We found that paternal education was associated with lower odds of stunting at 1, 4 and 7y, and infants who lived in extended families grew more from birth to 12 months, but had worst breastfeeding practices. Traditionally, nutritional interventions target lower income individuals, to alleviate nutritional and health gaps between lower and higher income individuals. Indeed, children living under extreme poverty had worse linear growth, noticeable at 7y, and traditional nutritional education interventions might not be enough to reduce the gap between the poorest and the better-off individuals. Nutritional status during infancy was a strong predictor of nutritional status during childhood, suggesting the potential of early interventions to avoid both stunting and overweight during childhood. Finally, more educated fathers had lower odds of having stunted children. Future studies should investigate the effectiveness of nutritional education programs targeting not only mothers, but also fathers.Ph.D.Includes bibliographical referencesby Thaisa Maria Simplicio Lemo
O sistema da dívida pública no debate do movimento da reforma sanitária brasileira: impactos sobre o (des)financiamento do SUS
Full text linkThis doctoral thesis intends to problematize in which aspects the debt system and its audit has been considered in the debates and productions in the field of collective health, especially with regard to the treatment given the question of the sub and unfinancing of the public policy of Health in Brazil context of implementation and development of the Brazilian national health system (SUS) as a public system responsible for effectiving health as a guaranteed right in the Constitution of the Federative Republic of Brazil promulgated in 1988. It is understood that the process of construction of the SUS has been given in a context of priority to the capital bearer of interest, especially in its fictitious form, in a dependent country, extremely unequal and with its historically restrictive economic policies, Focused on the fulfillment of inflationary targets and primary surplus, has implicated in containment and reduction of the financing of social protection policies, which have been strongly intended by the large capital project, reaching deeply the Brazilian Social security system, one of the greatest achievements listed in the Constitution of the Federative Republic of Brazil still in
force and permanently threatened and attacked in the process of counterinsurments since the decade of 1990 (including the central-left coalition governments) in the detriment of a solidarity network perspective of social protection. Our general objective is to analyze how the collective health/Brazilian Sanitary Reform Movement (MRSB) has been guiding the relationship between the debt system and the financing of the Brazilian national health system in the context of current capitalism in the Brazilian reality. With specific objectives, to analyze the relationship between financial globalization, fictitious capital and the debt system
in the Brazilian particularity; uncovering the nature of the State from the foundations of the critique of the economy; finally, to analyze the debt system in the context of the Health Reform discussion. This is a qualitative research based on Marx‟s historical and dialectical materialism. We used documentary research, examining publications of Revista Saúde em Debate from its first volume of publication (1976) to December 2019, whose collection constitutes the first and most expressive means of publication of the Brazilian sanitary reform movement. It is concluded that the issue of under and underfunding of public health policy in Brazil has been little discussed from the criticism of political economy, especially with regard to its relationship with the debt system in a totalizing perspective with the strategic objective of health as a universal guarantee in opposition to the idea of the monetization of health, as merchandise. It is observed that most analyzes of policy and financing are based on flexible Sanitary Reform formulations, reducing underfinancing to the fiscal crisis, with the absence of works that deeply discussed the relationship between the public debt system and the financing of public policy of health in Brazil. Finally, it points out the need to reposition the Brazilian Health Reform in the field of the more general struggle of the working class, contesting analyzes that reaffirm flexible formulations to recompose the discussion and the struggle that the realization of health as a right presupposes the overcoming of class SocietyA presente tese problematiza em que aspectos o sistema da dívida e sua auditoria tem sido considerado nos debates e produções no campo da saúde coletiva, sobretudo no que diz respeito ao sub financiamento / desfinanciamento da Política de Saúde no Brasil contexto de implantação e desenvolvimento do Sistema único de Saúde (SUS) enquanto sistema público responsável para efetivar a saúde como direito assegurado na CF de 1988. Compreende-se que o processo de construção do SUS tem se dado em um contexto de prioridade ao capital portador de juros, especialmente em sua forma fictícia, num país dependente, extremamente desigual e com suas políticas econômicas historicamente restritivas, voltadas ao cumprimento de metas inflacionárias e de superávit primário, tem implicado em contenção e redução do financiamento das políticas de proteção social, as quais tem sido fortemente tencionada pelo projeto do grande capital, atingindo profundamente o sistema de seguridade social brasileira, uma das maiores conquistas insculpida na Carta Magna ainda vigente e permanentemente ameaçada e atacada no processo de contrarreformas desde a década de 1990 (inclusive nos governos de coalizão de centro-esquerda) em detrimento de uma perspectiva de rede solidária de proteção social. Nosso objetivo geral consiste em analisar como a saúde coletiva / Movimento da Reforma Sanitária Brasileira (MRSB) vem pautando a relação entre o sistema da dívida e o financiamento do SUS no âmbito do capitalismo contemporâneo na realidade brasileira. Tendo como objetivos específicos, analisar a relação entre a mundialização financeira, o capital fictício e o sistema da dívida na particularidade brasileira;desvelar a natureza do Estado a partir dos fundamentos da crítica da economia; como também analisar o sistema da dívida no âmbito do debate da Reforma Sanitária. Trata-se de uma pesquisa qualitativa, baseada no materialismo histórico e dialético de Marx. Utilizamos à análise documental, examinando publicações da Revista Saúde em Debate deste o seu primeiro volume de publicação (1976) até dezembro de 2019, cujo acervo constitui o primeiro e mais expressivo meio de publicação do MRSB. Conclui-se que a questão do sub e desfinanciamento da política de saúde no Brasil vem sendo pouco problematizada a partir da crítica da economia política, sobretudo no que se refere a relacioná-la com o sistema da dívida numa perspectiva de análise totalizante no horizonte estratégico da saúde como um bem em oposição a saúde como custo, como mercadoria. Constata-se que a maioria das analises da politica e do financiamento se alinham a formulaçoes da Reforma Sanitária flexibilizada, reduzindo o desfinanciamento a crise fiscal, com poucas obras discutindo profundamente a relação entre o sistema da dívida pública e o financiamento da politica de saúde no Brasil. Indicando a necessidade de reposicionar a Reforma Sanitária Brasileira no campo da luta mais geral da classe trabalhadora, contestando análises que requentam formulações flexibilizadas de forma a recompor o debate e a luta de que a efetivação da saude como direito requer a superação da sociedade de classes
Helicopter nonlinear flight control: An acceleration measurements-based approach using incremental nonlinear dynamic inversion
No full textDue to the inherent instabilities and nonlinearities of rotorcraft dynamics, its changing properties during flight and the difficulties to predict its aerodynamics with high levels of fidelity, helicopter flight control requires strategies that allow to cope with the nonlinearities of the model and assure robustness in the presence of inaccuracies and changes in configuration. The control laws developed in the last years normally concern a complex architecture based on an approximate model inversion, with a robust control synthesis or adaptive elements to compensate for the inversion error. In this thesis, a novel approach based on an incremental model inversion is applied to simplify the design of helicopter flight controllers. With the adopted strategy, by employing the feedback of acceleration measurements to avoid the need for information relative to aerodynamic changes in the rotorcraft, the controller does not need any model data that depends exclusively on the states of the system, thus enhancing its robustness to model uncertainties and disturbances. The control system is composed of a three time scale separated loops architecture that allows to provide navigational control of the vehicle. The overall system is tested by simulating several maneuvers with distinct agility levels commonly used for flying qualities analysis and an efficient tracking of the commanded references is achieved. Furthermore, with the robustness properties verified within the range of inaccuracies expected to be found in reality, the suggested method seems to be eligible for a potential practical implementation, even if only a simplified model of the vehicle is available.Control and SimulationAerospace Engineerin
Data on the mechanisms underlying succinate-induced aortic contraction
No full textAbstractWe describe the mechanisms underlying the vascular contraction induced by succinate. The data presented here are related to the article entitled “Pharmacological characterization of the mechanisms underlying the vascular effects of succinate” (L.N. Leite, N.A. Gonzaga, J.A. Simplicio, G.T. Vale, J.M. Carballido, J.C. Alves-Filho, C.R. Tirapelli, 2016) [1]. Succinate acts as a signaling molecule by binding to a G-protein-coupled receptor termed GPR91, “Citric acid cycle intermediates as ligands for orphan G-protein-coupled receptors” (W. He, F.J. Miao, D.C. Lin, R.T. Schwandner, Z. Wang, J. Gao, J.L. Chen, H. Tian, L. Ling, 2004) [2]. Here we include data on the contractile effect of succinate in the aorta. Succinate contracted both endothelium-intact and endothelium-denuded aortic rings isolated from male Wistar rats or C57BL/6 mice. Succinate was less effective at inducing contraction in arteries isolated from GPR91-deficient mice, when compared to its vascular effect in aortas from wild type mice. SB203508 (p38MAK inhibitor), SP600125 (JNK inhibitor) and Y27632 (Rho-kinase inhibitor) reduced succinate-induced contraction in both endothelium-intact and endothelium-denuded rat aortic rings, while PD98059 (ERK1/2 inhibitor) did not affect succinate-induced contraction. The contractile response induced by succinate on endothelium-intact and endothelium-denuded rat aortic rings was reduced by indomethacin (non-selective cyclooxygenase inhibitor), H7 (protein kinase C inhibitor), verapamil (Ca2+ channel blocker) and tiron (superoxide anion scavenger)
Environmental toxicity, redox signaling and lung inflammation:the role of glutathione
Full text linkGlutathione (gamma-glutamyl-cysteinyl-glycine, GSH) is the most abundant intracellular antioxidant thiol and is central to redox defense during oxidative stress. GSH metabolism is tightly regulated and has been implicated in redox signaling and also in protection against environmental oxidant-mediated injury. Changes in the ratio of the reduced and disulfide form (GSH/GSSG) can affect signaling pathways that participate in a broad array of physiological responses from cell proliferation, autophagy and apoptosis to gene expression that involve H(2)O(2) as a second messenger. Oxidative stress due to oxidant/antioxidant imbalance and also due to environmental oxidants is an important component during inflammation and respiratory diseases such as chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis, acute respiratory distress syndrome, and asthma. It is known to activate multiple stress kinase pathways and redox-sensitive transcription factors such as Nrf2, NF-kappaB and AP-1, which differentially regulate the genes for pro-inflammatory cytokines as well as the protective antioxidant genes. Understanding the regulatory mechanisms for the induction of antioxidants, such as GSH, versus pro-inflammatory mediators at sites of oxidant-directed injuries may allow for the development of novel therapies which will allow pharmacological manipulation of GSH synthesis during inflammation and oxidative injury. This article features the current knowledge about the role of GSH in redox signaling, GSH biosynthesis and particularly the regulation of transcription factor Nrf2 by GSH and downstream signaling during oxidative stress and inflammation in various pulmonary diseases. We also discussed the current therapeutic clinical trials using GSH and other thiol compounds, such as N-acetyl-l-cysteine, fudosteine, carbocysteine, erdosteine in environment-induced airways disease

We start from the transcendental phenomenological tradition of Edmund Husserl, the existential phenomenology of Martin Heidegger and the phenomenology of corporeity of Maurice Merleau-Ponty. Despite having a long educational tradition in other countries, in Brazil, phenomenological approaches are little used in education. A phenomenological education is important, as it enables students to experience the perception of phenomena around them through bodily sensory experiences. To illustrate how this approach has favored experiencing in education, we carried out an overview of the historical tradition of English, German, Dutch and Brazilian speaking phenomenologists who articulated/articulated phenomenology to education. This approach is presented as a possible way to deal with an education that is still restrictively based on cognition, disregarding the relationship between mind and body and their relationship with the world. This also applies to the context of Science Education, which in general restricts access to nature through Cartesian dualism. For the Cartesian dualism, in the search for understanding phenomena, experiences are left aside, limiting knowledge only to the subject-object, which makes our understanding of the world difficult. We defend that a phenomenological approach is an educational path that enables the perception of the life-world based on our bodily experiences, our interaction with each other and with the world in which we live. From Merleau-Ponty, we perceive founding characteristics of the Body that take it from object body to subject Body to become a proper or lived Body. So that we can understand the child from his own point of view, Merleau-Ponty describes him with two types of experiences: primary and primordial. The author also describes that the small child goes through an egocentrism, a sociability, a mirror stage, through imitation and as perceived from the adult. For being the first phenomenologist who saw the child from the child's point of view, we propose, based on Merleau-Ponty's Flower of Life in childhood and aesthetic experiences in Science Education, the rooting of aesthetic experiences in Science Education in childhood as an access to lifeworld

Ranibizumab and aflibercept intravitreal injection for treatment na\uefve and refractory macular oedema in branch retinal vein occlusion
No full text\ua9 The Author(s) 2020. Background: Branch retinal vein occlusion complicated by macular oedema is a common disease treated with intravitreal injection of anti-vascular endothelial growth factor. Controversy exists surrounding anti-vascular endothelial growth factor selection for both treatment na\uefve and refractory cases. Methods: A retrospective electronic medical record review at a single UK centre generated a cohort of 259 treatment na\uefve eyes from 258 patients receiving ranibizumab, aflibercept or a combination (n = 83, 97 and 79, respectively) from 2013 to 2018 with ⩾6 months follow-up. Number of intravitreal injections, visual acuity and macular oedema presence were noted at 3, 6, 12, 24, 36 and 48 months. A subgroup analysis examined refractory cases switched from ranibizumab to aflibercept (n = 77) or maintained on ranibizumab (n = 35). Results: Eyes receiving ranibizumab or aflibercept had equivocal vision gain at 1 year, 8.0 (95% CI 5.0−11.0) and 9.6 (7.2−12.1) Early Treatment of Diabetic Retinopathy Study letters, respectively. About 35.6% had no macular oedema at 12 months with ranibizumab compared with 50.0% with aflibercept (p = 0.07) following 5.1 (4.7–5.6) and 6.0 (5.6–6.4) intravitreal injections, respectively. Visual prognosis declined significantly as treatment delay extended (p = 0.003) which was only apparent with ⩾3 months delay. Eyes with refractory macular oedema also had equivocal functional and anatomical outcomes whether they were maintained on ranibizumab or switched to aflibercept. Conclusion: These real world data demonstrate more modest clinical improvements from anti-vascular endothelial growth factor treatment than reported in clinical trials. The functional outcomes of ranibizumab and aflibercept in both treatment na\uefve and refractory cases were equivocal while the anatomical outcomes of aflibercept may be superior
