O direito à informação e o (ainda restrito) espaço cidadão no Jornalismo Popular impresso

Este artigo objetiva mostrar como na era da informação o Jornalismo, muitas vezes, negligencia o estímulo ao exercício da cidadania, em especial o Jornalismo realizado pelos meios de Comunicação de grande circulação. Estes veículos, em geral, não priorizam temas que colaboram para a formação e o espírito crítico. A análise será focada nos jornais ditos populares, em especial o Super Notícia, periódico fundado em 2002, que se tornou o veículo impresso mais vendido no país, mas com circulação restrita aos municípios mineiros. A pertinência do assunto se dá já que os periódicos populares apresentam grande circulação e, muitas vezes, são a única fonte de leitura das chamadas classes subalternas. Para o estudo, utilizamos a Análise de Conteúdo. Entendemos que o espaço para o Jornalismo Comunitário é restrito, enquanto há ênfase em assuntos relacionados com o crime, os astros de TV e o futebol. No entanto, é preciso buscar este espaço e não apenas ficar no campo da crítica

Design and baseline characteristics of the finerenone in reducing cardiovascular mortality and morbidity in diabetic kidney disease trial

Background: Among people with diabetes, those with kidney disease have exceptionally high rates of cardiovascular (CV) morbidity and mortality and progression of their underlying kidney disease. Finerenone is a novel, nonsteroidal, selective mineralocorticoid receptor antagonist that has shown to reduce albuminuria in type 2 diabetes (T2D) patients with chronic kidney disease (CKD) while revealing only a low risk of hyperkalemia. However, the effect of finerenone on CV and renal outcomes has not yet been investigated in long-term trials. Patients and Methods: The Finerenone in Reducing CV Mortality and Morbidity in Diabetic Kidney Disease (FIGARO-DKD) trial aims to assess the efficacy and safety of finerenone compared to placebo at reducing clinically important CV and renal outcomes in T2D patients with CKD. FIGARO-DKD is a randomized, double-blind, placebo-controlled, parallel-group, event-driven trial running in 47 countries with an expected duration of approximately 6 years. FIGARO-DKD randomized 7,437 patients with an estimated glomerular filtration rate >= 25 mL/min/1.73 m(2) and albuminuria (urinary albumin-to-creatinine ratio >= 30 to <= 5,000 mg/g). The study has at least 90% power to detect a 20% reduction in the risk of the primary outcome (overall two-sided significance level alpha = 0.05), the composite of time to first occurrence of CV death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure. Conclusions: FIGARO-DKD will determine whether an optimally treated cohort of T2D patients with CKD at high risk of CV and renal events will experience cardiorenal benefits with the addition of finerenone to their treatment regimen.

Morphological, physical, chemical and mineralogical characterization of calcareus mine spoils of the Irati Formation - Region of Piracicaba (SP)

Com o objetivo de fazer uma caracterização preliminar dos rejeitos de mineração de calcário e de observar a evolução deste material em função do tempo, foi escolhida uma jazida de calcário pertencente à Formação Irati (Permiano) no município de Saltinho - SP. Foram selecionados 3 montes de deposição de rejeitos com 2, 15 e 32 anos. O monte de 2 anos é formado por fragmentos de folhelhos e calcários com sílex e blocos argilosos. Os de 15 e 32 anos são constituídos principalmente de fragmentos de folhelhos e calcários com sílex. Foram abertas 5 trincheiras: Uma no monte de 2 anos (P1) sobre a cobertura de transição entre gramíneas e leucena, uma no monte de 15 anos (P2) sobre a cobertura de leucena e três no monte de 32 anos (P3, P4 e PS), sendo duas delas sobre a cobertura de leucena (P3 e P4) e uma terceira (P5) sobre a cobertura de pastagem consorciada gramíneas/leucena. Observou-se a ocorrência de horizonte A com 3 cm de espessura e com estrutura granular predominantemente fraca em P1 (2 anos). Nos montes formados por fragmentos rochosos, a estruturação não foi evidenciada em P2 (15 anos) e somente no monte com 32 anos observou-se o horizonte A com cerca de 3 cm de espessura. Os principais resultados obtidos apontam uma evolução da estrutura mais acelerada no banco onde os fragmentos rochosos são mesclados com material argiloso. As análises de granulometria apontam que ocorre rápida fragmentação das rochas próximo à superfície dos bancos e as análises químicas indicam lixiviação de Ca, Na e S-SO4 (salvo Ca em P1 (2 anos)) e aumento dos teores de K, do carbono orgânico e do nitrogênio na superfície de todos os perfis. Predomina pH ligeiramente ácido em todos os perfis. As concentrações de P, os valores de CTC e V% são elevados em todos os perfis estudados. A fragmentação das rochas, o grau de estruturação na superfície destes montes, a lixiviação de Ca, Na e S-SO4, a concentração de P, o acúmulo de K, carbono orgânico e nitrogênio são incrementados com a idade dos montes de rejeito. A mineralogia predominante destes solos reflete a do material de origem. Predomina, na fração areia, fragmentos de folhelhos, calcário e sílex sendo que, na areia muito fina, encontra-se fragmentos de sílica amorfa, quartzo e alguns indícios de feldspatos e mica. Na fração silte, além do quartzo, encontram-se os feldspatos. A mica é melhor evidenciada na fração silte através das análises por MEV. A fração argila é composta principalmente de esmectita, seguida de ilita. Um argila-mineral do tipo 1: 1 é discretamente evidenciado, porém ocorre com maior nitidez nos horizontes superficiais dos perfis P2 (15 anos), P3, P4 e PS (32 anos), sugerindo que esse mineral pode ter sido formado a partir do intemperismo de minerais presentes no material de origem.With the objective of doing a preliminary characterization of the calcareus mine spoil (lrati Formation - Permiane) and of observing the evolution of this material in function of time, a area of extraction of limestone in the municipal district of Saltinho (SP) was chosen. Three spoil banks were selected with 2, 15 and 32 years old. The 2 years old bank is formed of shale and limestone with silex rock fragments mixed with clay blocks. The 15 and 32 years old banks are basically formed mainly of fragments of shale and limestone cemented with silex. Five pits were openned in the following banks: one in the 2 years old bank (P1) on a grass - leucena transition cover; one in the 15 years old banck (P2) on a leucena cover and three in the 32 year-old bank (P3, P4 and P5), being two of them on leucena (P3 and P4) and the third one (P5) on grasses/leucena consorciation. We observed the occurrence of a weak granular structure A horizon with 3 cm of thickness in P1 (2 years). In the banks formed by rock fragments, no structure was evidenced in P2 (15 years old) and only in the 32 years-old banks the A horizon was observed with about 3 cm of thickness. The main results show an faster evolution of the structure in the bank made up of rock fragments mixed with clay materials. The grannulometrical analysis show a fast fragmentation of the rocks occurring near the surface of the profiles and the chemical analyses indicate leaching of Ca, Na and S-SO4 (safe Ca in P1 (2 years old)) and a increase of K, organic carbon and nitrogen in the mine soil surface. The pH is lightly acid to lightly basic in all the profiles. The P concentration, CEC and V% values are high in these mine soils. The rock fragmentation at the surface of these banks, the degree of structure development, the Ca, Na and S-SO4 leaching, the increaseing P and K concentration, organic carbon and nitrogen acumulation increase with the age of the bancks. The predominant mineralogy of these soils reflects the parental materials. Shale, limestone and silex fragments predominate in the sand fraction, and in the very fine sand, fragments of amorphous silica, quartz, few feldspates and traces of mica was observed. Besides the quartz, feldspates are found in the silt fraction. Mica is better evidenced by SEM micrographs in the silt fraction. The clay fraction is composed mainly of smectite, followed by ilite. A small 1: 1 clay mineral peak was indentified. This peak appears only in the superficial horizons of the P2 (15 years old), P3 P4 and P5 (32 years old) profiles and it suggests that this mineral can be formed from the weathering of minerals presents in the parental rocks

Sistemas de manejo do solo na recuperação de uma pastagem degradada em Rondônia Soil management systems in the recovery of a degraded pasture in Rondônia

Na região amazônica, pastagens formadas e conduzidas de forma inadequada perdem a produtividade durante os primeiros anos em razão de superpastejo, ausência de adubação e de manutenção e emprego de espécies inadequadas para as condições edafoflorísticas da região. O objetivo deste estudo foi quantificar as modificações ocasionadas por diferentes sistemas de manejo nos atributos físicos de um Latossolo Vermelho-Amarelo (LVA), sob pastagem degradada no Estado de Rondônia, RO. Os sistemas de manejo utilizados nos tratamentos foram: T = testemunha; G = gradagem + NPK + micronutrientes; H = herbicida + NK + micronutrientes; A = plantio direto de arroz + NPK + micronutrientes; e S = plantio direto de soja + NPK + micronutrientes. O delineamento experimental foi em blocos ao acaso com quatro repetições. Para avaliar os tratamentos, amostras com estrutura indeformada foram coletadas em três profundidades (0-0,10; 0,10-0,20 e 0,20-0,30 m) para determinar a curva de retenção da água no solo, densidade do solo, resistência do solo à penetração de raízes, macroporosidade, microporosidade, porosidade total, estimativa do intervalo hídrico ótimo (IHO), densidade máxima do solo (Dsmax) e densidade relativa do solo (Dsrel). Os sistemas de manejo do solo adotados na recuperação da pastagem não proporcionaram melhorias significativas nos atributos físicos do solo, 40 meses após a implantação dos tratamentos. Em todos os sistemas de manejo, foram encontrados valores de densidade do solo acima do considerado ideal (1,40 Mg m-3) e abaixo do crítico (1,75 Mg m-3). Todos os sistemas de manejo apresentaram valores de densidade do solo relativa (Dsrel) acima do valor adotado como crítico (Dsrel = 86 %), exceto no sistema em que foi realizado o preparo do solo na profundidade de 0-0,10 m. A qualidade física do solo, avaliada pelo IHO, diminuiu com o aumento da profundidade do solo.In the Amazon region, pastures provide a satisfactory grass yield in the first years. Over time, overgrazing by livestock, the lack of pasture maintenance and choice of regionally unsuitable forage species can lead to soil degradation. The objective of this study was to evaluate the effect of different soil management systems on some soil physical properties of a Red-Yellow Oxisol (LVA) under degraded pasture, in the State of Rondônia (RO). The soil management systems were T = control; G = harrowing + NPK + micronutrients; H = herbicide + NK + micronutrients; A = no-tillage rice + NPK + micronutrients; S = no-tillage soybean + NPK + micronutrients. The experiment was arranged in a randomized block design with four replications and five soil management systems. Undisturbed soil samples were collected (layers 0-0.10, 0.10-0.20 and 0.20-0.30 m) to assess soil water retention capacity, soil bulk density, soil penetration resistance, macroporosity, microporosity and total porosity, and to calculate the least limiting water range (LLWR), maximum soil bulk density (Dsmax), and relative soil bulk density (Dsrel). The management systems did not improve the soil physical properties, 40 months after the beginning of experiment. In all treatments, soil bulk density was higher than the ideal value (1.40 Mg m-3) and lower than critical (1.70 Mg m-3). With exception of G (0-0.10 m), the Dsrel exceeded the critical level (Dsrel = 86 %) in all soil management systems. The evaluation of the LLWR showed that the physical quality decreased with increasing soil depth

Aspectos epidemiológicos, fatores de risco e achados clinicopatológicos do melanoma em cães no Sertão, Nordeste do Brasil

Background: Melanoma is a malignant neoplasm that arises from melanocytes and malanoblasts. It is also more frequently reported in dogs than in other species. They may arise from melanocytes in the skin, on the surfaces of the mucous membranes, and eyes. The aim of this study was to describe the epidemiological aspects, risk factors and clinicopathological findings of melanoma in dogs in the backlands, northeastern Brazil. Materials, Methods &amp; Results: A retrospective study was carried out in all biopsy samples and necropsy examinations of dogs, from January 2003 to December 2021, at the Animal Pathology Laboratory of the Federal University of Campina Grande, Patos, Paraiba, northeastern Brazil. Epidemiological data, clinical signs, and gross lesions were reviewed from the diagnostic laboratory reports. Samples of the skin, lymph nodes, central nervous system and organs of the thoracic and abdominal cavities were fixed in 10% buffered formalin, processed routinely for histopathology, embedded in paraffin wax, cut into 4 µm sections, and stained with hematoxylin and eosin (HE). Histological sections were also submitted to immunohistochemistry with the primary antibody anti-Melan A. Of the 4717 records found, 1158 (24.5%) were diagnosed with neoplasms, of which 48 (4.14%) cases were of melanoma. Of this total, 28 (58.3%) dogs were elderly, 19 (39.6%) were adults, and 1 (2.1%) was young. Mixed breed animals were the most affected (42.6%), followed by the pinscher breed (19.1%). According to the anatomical region, the most affected site was the skin (38/53=71.7%), followed by the oral cavity (12/53=22.65%) and the eyes (3/53=5.7%). Grossly, the skin lesions were characterized by exophytic and usually blackened, sometimes irregular and firm, nodules. At cut, they had a smooth, compact and blackened surface. Lesions in the oral cavity were characterized by blackened, irregular and infiltrating nodules or masses. The ocular lesions were always unilateral and were characterized by an enlarged and diffusely blackened eyeball, with areas of ulceration and subversion of tissue architecture. In 5 animals there was more than one anatomical site affected, totaling 53 lesions. In 9 (17%) cases, metastases were identified, 8 in regional lymph nodes and 1 in the lung. Histopathology showed a densely non-encapsulated, poorly delimited, expansive and infiltrative neoplasm, composed of neoplastic cells arranged in islands or nests and supported by fibrovascular stroma, containing a variable amount of brownish pigment (melanin). Immunohistochemistry showed strong immunostaining of the neoplastic cells in brown by the anti-Melan A antibody. Discussion: The diagnosis of melanoma was established based on epidemiological, clinical, anatomopathological, and immunohistochemical findings. Gender is not a predisposing factor, and although there was no statistically significant relationship, males were more affected. Senescence is a conditioning risk factor. Elderly animals were more affected (P &lt; 0.0001) than adult ones, with OR = 4.38; and young ones (P = 0.0051), with OR = 12.65. Some breeds, especially those with marked skin pigmentation, were more affected, however the most affected ones in this survey were pinscher and poodle. Cutaneous melanoma accounted for almost 72% of cases, contesting recent studies where oral cavity melanoma was more frequent. Therefore, it is believed that the climatic conditions of the backlands sub-region, in northeastern Brazil, associated with the individual characteristics of the dogs, are involved in the development of these neoplasms, since the climate is predominantly dry, with high temperatures throughout the year, with maximums that can reach 40ºC, favoring the exposure to high incidence of ultraviolet radiation.

Digestive and productive utilization of semi- simplifield hay diets enriched with vinasse for growing rabbits

The objective of this study was to evaluate the influence of two qualities of Tifton 85 hay enriched or not with vinasse in semi-simplified diets on the apparent nutrient digestibility, composition and nutritional contribution of cecotropes, productive performance, and carcass, edible viscera and gastrointestinal tract yields of growing New Zealand White rabbits. Fresh vinasse at a proportion of 2:1 was added to the diets containing high-quality (HQV) and low-quality Tifton 85 hay (LQV). The control diets containing high-quality (HQ) and low-quality Tifton 85 (LQ) were not enriched with vinasse. In the digestibility assay, the semi-simplified diets were not influenced (P>0.05) by the quality of hay or by the addition of vinasse, except for the digestibility coefficients of mineral matter, which were 52.31%, 51.13%, 54.45% and 46.73% for treatments HQ, HQV, LQ and LQV, respectively. In the cecotrophy assay, production, chemical composition or nutritional contribution was not altered (P>0.05) in any of the treatments. In the performance assay, no significant difference (P>0.05) was observed in productive parameters or carcass traits, except for kidney weight (P<0.05). It is therefore possible to include vinasse in hay diets without compromising the performance, nutritional contribution of cecotropes or digestibility of growing New Zealand White rabbits
