Este estudo teve como objetivo evidenciar a vivência de estudantes quilombolas dos cursos de Biblioteconomia quanto ao acesso à informação e ao ato de ler, segundo uma concepção da importância das ...atividades mediadoras. Quanto à metodologia, a pesquisa caracteriza-se como descritiva e teve como método o levantamento de campo. Os dados foram coletados através de questionário online junto aos discentes vinculados aos cursos de Biblioteconomia, nas modalidades presencial e à distância, no Brasil, e analisados a partir da abordagem qualitativa. A trajetória investigativa desta pesquisa conduziu à identificação de que a totalidade dos(as) participantes deste estudo, 17 discentes, tem a percepção quanto à importância das atividades de mediação e da biblioteca para comunidade quilombola, apesar de oito deles(as) indicarem que não tiveram acesso aos ambientes informacionais durante a formação nos ensinos fundamental e médio. Considera-se que a postura protagonista desses(as) discentes, como futuros(as) bibliotecários(as), e de demais agentes mediadores podem favorecer a realização de atividades de mediação da informação e mediação da leitura que tenham por objetivo ampliar as possibilidades de acesso e apropriação dos dispositivos informacionais por parte dos(as) integrantes das comunidades quilombolas, de modo a favorecer o alcance do protagonismo cultural e da liberdade desses povos
Ao analisar os microdados da PNAD-C (2012-2022), este artigo investiga as oportunidades educacionais e de acesso ao trabalho entre os jovens. A taxa líquida de matrícula no ensino médio avançou entre ...os jovens com 15 a 17 anos, mas um modelo de transições indica que as desigualdades raciais no acesso ao ensino médio aumentaram entre 2017 e 2022, enquanto a escolaridade da mãe condiciona a formação básica na idade adequada. Ademais, o papel do jovem-estudante se consolidou entre os adolescentes com 15 a 17 anos, mas, para o grupo com 18 a 24 anos, a exclusão dos estudos e do trabalho prevalece entre os jovens negros e do sexo feminino. Por fim, a residência com crianças é decisiva para o acesso a oportunidades entre as mulheres pobres.
Adipose tissue is considered an endocrine organ that promotes excessive production of reactive oxygen species when in excess, thus contributing to lipid peroxidation. Magnesium deficiency contributes ...to the development of oxidative stress in obese individuals, as this mineral plays a role as an antioxidant, participates as a cofactor of several enzymes, maintains cell membrane stability and mitigates the effects of oxidative stress. The objective of this review is to bring together updated information on the participation of magnesium in the oxidative stress present in obesity. We conducted a search of articles published in the PubMed, SciELO and LILACS databases, using the keywords ‘magnesium’, ‘oxidative stress’, ‘malondialdehyde’, ‘superoxide dismutase’, ‘glutathione peroxidase’, ‘reactive oxygen species’, ‘inflammation’ and ‘obesity’. The studies show that obese subjects have low serum concentrations of magnesium, as well as high concentrations of oxidative stress marker in these individuals. Furthermore, it is evident that the adequate intake of magnesium contributes to its appropriate homeostasis in the body. Thus, this review of current research can help define the need for intervention with supplementation of this mineral for the prevention and treatment of disorders associated with this chronic disease.
We investigated the impact of socioeconomic inequalities on chronic pain of older adults according to sex.
This population-based cross-sectional study used survey data from the 2015 cohort of the ...SABE Study (Saúde, Bem-estar e Envelhecimento), Brazil. Socioeconomic status was examined at individual level (educational attainment, financial independence, and race/skin color) and contextual level (Human Development Index). We analyzed the association between variables using the chi-square test and the Rao & Scott correction. Logistic regression models were adjusted for risk factors.
The study comprised 1,207 older adults representing 1,365,514 residents 60≥ years of age in the city of São Paulo. Chronic pain was more frequent in females (27.2%) than in males (14.5%) (p<0.001). Females evidenced the worst self-perception of pain, especially those of the most vulnerable socioeconomic strata. Social inequalities impacted chronic pain in different ways between sexes. Among females, unfavorable living conditions (OR = 1.59; 95%CI 1.07; 2,37) and Blacks/Browns females were most likely to have chronic pain (OR = 1.32; 95%CI 1.01; 1.74). Among males, only the individual aspects were significant for the occurrence of chronic pain, such as low educational attainment (OR = 1.88; 95%CI 1.16; 3.04) and insufficient income (OR = 1.63; 95%CI 1.01; 2.62).
The potential for inequality was greater for females than for males reflecting structural factors inherent in a highly unequal society. Conclusions: Equity-oriented health policies are critical to preventing pain in human aging.

RESUMO Objetivo: reportar as evidências científicas do impacto da afasia no Processamento Auditivo Central e mapear a contribuição do Treinamento Auditivo para a população afásica. Métodos: trata-se ...de uma revisão de escopo realizada nas bases de dados nacionais e internacionais: Scielo, Lilacs, Pubmed, Scopus, Cochrane Library e com uma busca adicional à literatura cinzenta no Google Scholar e Open Grey. Os critérios de inclusão abrangeram artigos que abordassem a interface do processamento auditivo central e afasia, excluindo-se as duplicações, artigos de revisão da literatura e resumos científicos. Revisão de Literatura: selecionaram-se 13 artigos que cumpriram os critérios de elegibilidade deste estudo. Dos artigos selecionados, sete apresentaram a avaliação do Processamento Auditivo Central, quatro apresentaram os exames eletrofisiológicos - como os exames de Potencial Evocado Auditivo de Tronco Encefálico (PEATE) e Potencial Evocado Auditivo de Longa Latência (PEALL) - para avaliação da via auditiva e apenas um estudo analisou a intervenção dos indivíduos afásicos por meio do treinamento auditivo. Conclusão: as evidências científicas apontam importante alteração no Processamento Auditivo Central dos afásicos, apresentando prejuízos nas habilidades auditivas de figura-fundo, fechamento auditivo, resolução e ordenação temporal e integração binaural. Ainda, demonstra-se como relevante a avaliação do processamento, devido à contribuição do Treinamento Auditivo nas terapias fonoaudiológicas para um melhor prognóstico na reabilitação das afasias.
ABSTRACT Purpose: to report scientific evidence on the impact of aphasia on central auditory processing and map the contribution of auditory training to aphasic individuals. Methods: a scoping review approaching national and international databases (SciELO, LILACS, PubMed, Scopus, and Cochrane Library) and the gray literature (Google Scholar and Open Grey). The inclusion criteria covered articles that addressed the interface between central auditory processing and aphasia, excluding duplicates, literature reviews, and scientific abstracts. Literature Review: the review comprised 13 articles that met the eligibility criteria for this study. Seven of the selected articles assessed central auditory processing, four used electrophysiological examinations (such as auditory brainstem response and long-latency auditory evoked potentials) to assess the auditory pathway, and only one analyzed the intervention in aphasic individuals with auditory training. Conclusion: scientific evidence points to an important change in aphasic people’s central auditory processing, with impaired figure-ground, auditory closure, temporal resolution and ordering, and binaural integration. Moreover, it is relevant to assess auditory processing, given the contribution of auditory training in speech-language-hearing therapy for a better prognosis in the rehabilitation of aphasia.
Obesity is a major public health problem, and there is increasing scientific interest in its mechanisms, as well as a search for new compounds with antioxidant and anti-inflammatory properties that ...can minimize the metabolic complications associated with its pathology. One potential source of these compounds is natural products; Among these, flavonoids are a promising group of natural substances. Flavonoids are active constituents with diverse biological activities and are widely found in plants kingdom. Numerous studies have shown that flavonoids can effectively inhibit obesity and related metabolic disorders. The review synthesizes recent evidence in respect of progress in the understanding of the anti-obesity effects of flavonoids. Such effects which occurs through the modulation of proteins, genes and transcriptional factors involved in decreasing lipogenesis, increasing lipolysis, expenditure energy, stimulating fatty acids B-oxidation, digestion and metabolism of carbohydrates. In addition to mitigating inflammatory responses and suppress oxidative stress. A better understanding of the modulating effects and mechanisms of flavonoids in relation to obesity will allow us to better use these compounds to treat or even prevent obesity and its associated comorbidities.
Abstract
The purpose of this article is to analyse the circumstances in which the National Health Policy for Persons with Disabilities (PNSPCD) came into place in 2002 and the factors supporting or ...impeding its implementation from 2002 to 2018. The analysis was based on the Comprehensive Policy Analysis Model proposed by Walt and Gilson and focussed on understanding the context, process, content and actors involved in the formulation and implementation of the Policy. Data were obtained from two sources: document analysis of the key relevant documents and seven key informant interviews. Content analysis was undertaken using the Condensation of Meanings technique. The research demonstrates that the development and implementation of PNSPCD is marked by advances and retreats, determined, above all, by national and international macro-political decisions. The policy was formulated during Fernando Henrique’s governments, under pressure from social movements and the international agenda and constituted a breakthrough for the rights of persons with disabilities. However, progress on implementation only took place under subsequent centre-left governments with the establishment of a care network for people with disabilities and a defined specific budget. These developments resulted from the mobilization of social movements, the ratification of the United Nations Convention on the rights of people with disabilities and the adherence of these governments to the human rights agenda. The coming to power of ultra-right governments triggered fiscal austerity, a setback in the implementation of the care network and a weakening in the content of various social policies related to the care of people with disabilities. During this era, the political approach changed, with the attempt to evade the role of the State, and the perspective of guaranteeing social rights. Undoubtedly, the neoliberal offensive on social policies, especially the Unified Health System, is the main obstacle to the effective implementation of the PNPCD in Brazil.
Zn deficiency compromises its biological functions, its effect on the immune system and its antiviral activity, increasing vulnerability to infectious diseases. This narrative review aims at ...presenting and discussing functional aspects and possible mechanisms involved in the potential role of Zn in the immune response and antiviral activity for coronavirus infectious disease-19 (COVID-19) prevention and control. The searches were conducted in PubMed and Science Direct databases, using clinical trials, experimental studies in animals and humans, case–control studies, case series, letters to the editor, and review articles published in English, without restrictions on year of publication. Search approach was based on using the terms: ‘zinc’, ‘COVID-19’, ‘antiviral agents’, ‘immunologic factors’ and ‘respiratory tract infections’. Literature shows the importance of Zn as an essential mineral immunomodulator with relevant antiviral activity in the body. Thus, although there is still a scarcity of studies evaluating Zn supplementation in patients with COVID-19, the results on the topic show the necessity of controlling Zn mineral deficiency, as well as maintaining its homoeostasis in the body in order to strengthen the immune system and improve the prevention of highly complex viral infections, such as that of the COVID-19.
