Poéticas da proximidade : arte participativa de caráter dialógico na construção de situações de encontro no espaço público

A presente pesquisa envolve a análise de trabalhos que realizei entre 2012-2018 relacionados às questões da cidade contemporânea e à perda gradual de sua capacidade de promover encontros. Discuto como, na sociedade urbana contemporânea, espaços propícios ao encontro e à troca entre alteridades, tais como calçadas, praças e parques foram sendo substituídos por experiências individualizadas, praticadas em ambientes assépticos e dirigidos ao consumo massivo. A partir dessas inquietações, investigo de que forma processos artísticos participativos e de caráter dialógico possibilitam a ocorrência de situações de encontro no espaço público, examinando a ocorrência de tais processos como microacontecimentos cotidianos. Meu interesse parte do entendimento de que os projetos, ações e inserções desenvolvidos se constituem como modos de subjetivação capazes de encaminhar a construção daquilo que entendo como poéticas da proximidade.The present research involves the analysis of works that I performed between 2012-2018 related to contemporary city issues and the gradual loss of their capacity to promote meetings. I discuss how, in contemporary urban society, spaces conducive to meeting and exchanging between alterities, such as sidewalks, squares and parks were replaced by individualized experiences practiced in aseptic environments and directed to mass consumption. From these concerns, I investigate how participatory artistic processes and dialogical character enable the occurrence of situations of encounter in the public sphere, examining the occurrence of such processes as everyday micro events. My interest is based on the understanding that the projects, actions and insertions developed are forms of subjectivation capable of directing the construction of what I understand as poetics of proximity

Problemas puerperales en las mamas de madres seropositivas

Em virtude da recomendação de não amamentar, a mulher soropositiva para o HIV poderá enfrentar problemas mamários. Objetivou-se conhecer situações vivenciadas e reveladas por mulheres HIV positivas, diante da não-amamentação. Estudo qualitativo, com 15 mulheres com HIV/Aids, realizado em ambulatório de um hospital referência em Fortaleza, Ceará. Entrevistas gravadas tiveram seus conteúdos transcritos e analisados. As mães revelaram problemas com as mamas após o parto, como o ingurgitamento e dores neste local. Informaram ter recebido orientação no pré-natal para não amamentar, mas não houve continuidade do cuidado no pós-parto. Foi reduzido o uso de inibidores da lactação e enfaixamento das mamas. Para orientar as puérperas soropositivas, os profissionais de saúde devem adotar medidas adequadas. Também os serviços de saúde necessitam ampliar estratégias para minimizar os problemas emocionais decorrentes da não-amamentação, bem como do desconforto na mama puerperal.En virtud de la recomendación de no amamantar, la mujer seropositiva al HIV podrá sufrir problemas mamarios. Se planteó el objetivo de conocer situaciones vivenciadas y referidas por mujeres HIV positivas frente al hecho de no poder amamantar. El estudio fue de carácter cualitativo, con quince mujeres con HIV/AIDS, realizado en el Ambulatorio de un hospital referencial en Fortaleza, Ceará, Brasil. Las entrevistas fueron grabadas, y sus contenidos, transcriptos y analizados. Las madres refirieron problemas con las mamas después del parto, como ingurgitación y dolores en la zona. Informaron haber recibido orientación en la etapa prenatal para no amamantar, más no hubo continuidad del cuidado en la etapa posparto. El uso de inhibidores de la lactación y el fajado de las mamas fue escaso. Para orientar a las puérperas seropositivas, los profesionales de la salud deben adoptar medidas adecuadas. De igual modo, los servicios de salud necesitan ampliar estrategias para minimizar los problemas emocionales derivados del no amamantar, así como para la incomodidad de la mama puerperal.Given the recommendation not to breastfeed their infants, HIV-positive women may experience breast problems. The aim of the study was to gain knowledge regarding breast health as revealed by HIV+ women before the non-breast-feeding. This qualitative study was performed with 15 mothers with HIV/ AIDS in Fortaleza, Brazil. Recorded interviews were transcribed and analyzed. The mothers revealed problems with their breasts following childbirth, such as engorgement and pain in the breasts. They revealed that they received instruction in the course of prenatal care not to breastfeed; however, there was no further instruction or care in the postpartum period. The use of lactation inhibitors and bandaging (binding) of the breast were reduced. Health professionals should adopt appropriate measures to guide HIV- positive parturient women. Health services need to broaden strategies to minimize the current emotional problems resulting from non-breast-feeding, as well as the discomfort in the puerperal breast

Estudo da imunopatogenia das lesões no sistema nervoso central de cães naturalmente acometidos por leishmaniose visceral

Visceral leishmaniasis in dogs is described as a chronic disease whose main symptoms are progressive weigth loss, cachexy and dermatologic lesions. Recently, the disease has been associated to neurologic disorders. A total of 40 dogs with visceral leishmaniasis were divided into two groups. The first composed of dogs without neurological signs (n=30) and the second by dogs with neurological disorders (n=10). Brain samples were collected, stored in 10% buffered formalin and subjected to immunohistochemical examination for amastigotes forms of Leishmania (Leishmania) infantum chagasi, CD3+, CD4+ and CD8+ T lymphocytes and macrophages. Imunnohistochemistry evaluation revealed no amastigote forms of the parasite. CD3+ T lymphocytes were present in 24/30 (80%) dogs without neurological signs and in all dogs from the second group (p=0.0011). CD4+ and CD8+ were rarely observed, with CD4+ immunostaining in 10/40 (25%) dogs, from which half of them had neurological disease (p=0.0090). The presence of CD8+ was detected only in 4/10 (40%) dogs from neurological group (p=0.0021). Macrophages were detected in 38/40 (95%) dogs, without significant differences between groups (p=0.7664).A Leishmaniose visceral em cães é descrita como uma doença de caráter crônico na qual os principais sintomas são perda progressiva de peso, caquexia e lesões dermatológicas. Recentemente, a doença tem sido relacionada com alterações neurológicas. Um total de 40 cães portadores de leishmaniose visceral foi dividido em dois grupos. O primeiro composto por cães sem sintomas neurológicos (n=30) e o segundo grupo composto por cães com sintomas neurológicos (n=10). Amostras de encéfalo foram coletadas e armazenadas em formalina tamponada, para realização de imunoistoquímica para a pesquisa de formas amastigotas de Leishmania (Leishmania) infantum chagasi, linfócitos T CD3+, CD4+ e CD8+ e macrófagos. A reação de imunoistoquímica não revelou formas amastigotas do parasita. Linfócitos T estavam presentes em 24/30 (80%) dos cães sem sintomas neurológicos e em todos os cães do segundo grupo (p=0,0011). Linfócitos CD4+ e CD8+ raramente foram observados, apresentando imunomarcação para CD4+ em 10/40 (25%) dos cães e em metade dos animais do grupo neurológico (p=0,0090). A presença de CD8+ foi detectada em 4/10 (40%) cães com doenças neurológicas (p=0,0021). Macrófagos foram observados em 38/40 (95%) cães, sem diferença estatística significante entre os dois grupos (p= 0,7664)

Nitrogen efficiency in marandupalisadegrass pastures under increasing nitrogen levels

ABSTRACT: The use of nitrogen (N) in pastoral ecosystems leads to increased productivity, as it allows the plant to elongate its leaves and, therefore, grazing herbivores harvest the green leaves. However, there are very volatile N sources, which can be replaced by ammonium nitrate, which is less volatile and less dependent on the application in rainy days. The treatments are compound of Marandu palisade grass pastures managed under continuous stocking at a canopy height of 25 cm, with different levels of N fertilizer: 0, 75, and 150 kg ha-1year-1, as ammonium nitrate (32% of N), with four replicates (pastures) in a completely randomized design. Nitrogen uptake (54.9, 96.5, 113.8 kg N ha-1) and N nutrition index (0.67, 0.98, 1.15) were different between N level, respectively, 0, 75 and 150 kg ha-1 year-1. The N recovery (58.3, 40.9 %) differed between 75 and 150 kg ha-1 year-1, respectively. The dose of 75 kg N kg ha-1 year-1 results in better N utilization, while the dose of 150 kg N ha-1 year-1 enables greater stocking rate; therefore, requiring less grazing area

The control and prevention of COVID-19 transmission in children : a protocol for systematic review and meta-analysis

Background: The pandemic following the rapid spread of the new SARS-CoV-2 virus has hit all continents and caused thousands of deaths worldwide. Evidence has been published on epidemiological and clinical characteristics of population groups considered at risk; however, information for the other population groups, especially for the child population, is needed. In this context, this protocol describes a systematic review that will aim to identify the evidence on control and prevention of COVID-19 transmission among children and adolescents, as well as to describe the epidemiological profile and clinical and immunological characteristics of COVID-19 in this population. Methods: This protocol will be developed in accordance with PRISMA-P. The searches will be conducted in PubMed, Web of Science, ScienceDirect, EMBASE, and Scopus, seeking clinical trials. Observational studies and case reports with Children and adolescents (≤19 years) infected with SARS-CoV-2 will be included whether they report information on the control of prevention and COVID-19 transmission. Two independent researchers will perform the selection of articles, removal of duplication, and screening by Rayyan QCRI application. Cochrane's RoB 2.0, ROBINS-I, and CASP tools will be used to assess the risk of bias. Meta-analysis, subgroup analyses, and/or descriptive analyses will be carried out based on the data conditions included. Results: A high-quality synthesis of the available evidences on the epidemiological profile, the clinical and immunological characteristics involved in children, and adolescents diagnosed with COVID-19, as well as the participation of this population in the transmission dynamics of SARS-CoV-2 will be provided. Conclusion: This systematic review has an important relevance in the current context because it has a great potential to help the development of new control and prevention strategies in the pediatric population

Estudos Artísticos

Os quinze artigos que aqui se reúnem, nesta edição da Revista Croma, são também as propostas para uma nova política, esclarecida, crítica, e mais exigente. Podem observar-se padrões de intervenção, que partem de algumas dimensões comuns: a interpelação do observador, a criação de novos públicos, a proposta de contribuir para uma mudança alargada, partindo de questões a que não são alheias as problemáticas contemporâneas. As questões de género, a emancipação pós-colonial, a sustentabilidade, as migrações, a massificação, a globalização, o fim das ideologias e a ascensão do populismo, entre outras, constituem os contextos da atualidadeinfo:eu-repo/semantics/publishedVersio
