O radiojornalismo brasileiro: a notícia na Rádio Globo e na CBN
Analisa as mudanças ocorridas no radiojornalismo brasileiro até o surgimento das emissoras all news. O rádio deixa de ter o papel educativo, e a programação nas principais emissoras fica sobre o tripé notícia-esporte-serviço. O jornalismo aperfeiçoa-se, sendo construída uma linguagem apropriada para o meio. Essa linguagem é repleta de detalhes, devido às características próprias do rádio, a exemplo: imediatismo, dinamismo, baixo custo, necessidade da síntese, poder ser ouvido enquanto outra atividade é executada. A
tecnologia é um dos elementos essenciais para as principais mudanças, além das transformações políticas e econômicas. O estudo de caso de programas da Rádio Globo AM e da CBN visa mostrar as principais diferenças e abordagens do radiojornalismo entre duas emissoras com perfis distintos e do mesmo grupo empresarial
Solidago Gigantea Plants from Nonnative Ranges Compensate more in Response to Damage than Plants from the Native Range
Resistance and tolerance are two ways that plants cope with herbivory. Tolerance, the ability of a plant to regrow or reproduce after being consumed, has been studied less than resistance, but this trait varies widely among species and has considerable potential to affect the ecology of plant species. One particular aspect of tolerance, compensatory responses, can evolve rapidly in plant species; providing insight into interactions between consumers and plants. However, compensation by invasive species has rarely been explored. We compared compensatory responses to the effects of simulated herbivory expressed by plants from seven Solidago gigantea populations from the native North American range to that expressed by plants from nine populations from the nonnative European range. Populations were also collected along elevational gradients to compare ecotypic variation within and between ranges. Solidago plants from the nonnative range of Europe were more tolerant to herbivory than plants from the native range of North America. Furthermore, plants from European populations increased in total biomass and growth rate with elevation, but decreased in compensatory response. There were no relationships between elevation and growth or compensation for North American populations. Our results suggest that Solidago gigantea may have evolved to better compensate for herbivory damage in Europe, perhaps in response to a shift to greater proportion of attack from generalists. Our results also suggest a possible trade-off between rapid growth and compensation to damage in European populations but not in North American populations

Gastroesophageal Foreign Bodies in Dogs - Endoscopy and Surgical Removal
Background: Gastroesophageal foreign bodies (GFD) are commonly diagnosed in dogs and are considered an endoscopic emergency that, although not resulting in serious clinical sequelae or mortality, can compromise the health and well-being of the patient. The use of the digestive endoscopy for the diagnosis and treatment of GFD can be a valuable and viable alternative. There are cases of GFD in dogs for which the indicated treatment is surgery, which can be performed using minimally invasive or conventional techniques, associated or not with flexible endoscopy. The objective of this work is to describe 16 cases of GFD removal in dogs demonstrating the efficiency of upper digestive endoscopy.
Cases: Of the 16 GFD cases, 63% (10/16) were male and 37% (6/16) female. Most aged under 1 year (63%), puppies (5/16) and juveniles (5/16). The patient with the lowest body weight was a miniature pinscher weighing 0.8 kg (Case 14) and the heaviest was an American Pit Bull Terrier weighing 28 kg (Case 11), the mean body weight of patients diagnosed with GFD was 10.2 ± 6.7 kg. Small and medium breeds were more affected, 44.7% (7/16) and 44.7% (7/16), respectively, and large breeds (Golden Retrievier and Bull Terrier), from cases 1 and 4, the least affected, 12.6% (2/16) of the cases. The 16 patients underwent a 12 h food fast and a 4 h water fast, as gastrointestinal emptying in these cases of GFD can be influenced by these foreign bodies. All underwent general inhalation anesthesia with monitoring of physiological parameters (temperature, heart rate, respiratory rate, oxygen saturation and blood pressure) before, during and after EGD, being positioned in left lateral decubitus. The 16 canine patients with suspected GFD underwent EGD for diagnostic confirmation and removal of foreign bodies. Five esophageal FB were diagnosed, 31% (5/16), and 11 gastric FB, 69% (11/16). The most frequently diagnosed foreign bodies were bone and tissue, 37.5% (6/16) and 31% (5/16). Other foreign bodies were materials such as plastics, metals, rubber, foam and stone. Of the 16 cases of GFD, EGD efficiently treated 88% (14/16) without the need for hospitalization, with only supportive treatment for the remission of complications caused by the presence of foreign bodies in the gastroesophageal tract. The main complications related to the presence of GFD were esophagitis in 25% (4/16) of cases, gastritis in 38% (6/16) and both alterations in 13% (2/16).
Discussion: In this work, we can observe that more than a third of the clinical cases of treated dogs were diagnosed with GFD, demonstrating that these cases are common in the veterinary clinic. Most of these animals were males less than 1 year old. The improvement of learning in this category can lead these animals to exacerbated oral exploration of new objects. Most FBs were found in the stomach because they were of adequate size, consistency and shape for their passage through the esophagus, whereas esophageal FBs were all bone fragments of rigid consistency with diameters and sizes larger than the esophageal lumen. The interval between the ingestion of the object and the veterinary care can be decisive for the removal of the FB in the esophagus or stomach. Most gastric FBs removed were fabrics and plastics, flexible objects that can pass through the esophageal lumen more easily. Removal of GFD by endoscopy was performed with a high success rate, with only 2 cases being resolved by esophagostomy and gastrotomy. Flexible endoscopy proved to be an efficient technique for removing treated GFD, which can help remove FB during esophagotomy and be associated with rigid endoscopy. Patients recovered quickly and without complications, but it is important to emphasize that inadequate maneuvers and conducts can determine other outcomes. The use of endoscopy for GFD removal needs to be more popularized, as it can ensure better results for dogs treated with GFD.

A síndrome de burnout e suas consequências nos profissionais de saúde: uma revisão de literatura / Burnout syndrome and its consequences on health professionals: a literature review
1 INTRODUÇÃOHodiernamente, observa-se que o alto estresse emocional é fator de predisposição a doenças como fadiga, depressão, distúrbios de sono e Síndrome de Bournout (SB). A SB caracteriza-se como uma desordem psicossocial decorrente de fatores estressantes severos no ambiente de trabalho. Suas repercussões atingem principalmente profissionais da saúde, devido a responsabilidade de lidar com vidas constantemente. Pacientes sofrem com o déficit de qualidade do atendimento que acometem esses profissionais. Portanto, se não diagnosticada e tratada precocemente, pode resultar em problemas maiores que afetam o indivíduo como um todo. 2 OBJETIVOAnalisar artigos científicos relevantes na literatura científica sobre a Síndrome de Burnout, no que tange às suas consequências, especificamente nos profissionais de saúde e de que forma isso impacta na sociedade. 3 MATERIAIS E MÉTODOSRealizou-se uma revisão integrativa de literatura, através das plataformas: SciELO, Lilacs e BVS nos idiomas inglês e português, em julho de 2020. Na metodologia da busca, usou-se os seguintes descritores: Síndrome de Burnout [Burnout Syndrome], Saúde mental [mental health] e profissionais de saúde [health professionals]. Na leitura dos 12 artigos que atenderam aos critérios de inclusão, 3 foram selecionados para compor este resumo. 4 RESULTADOS E DISCUSSÃOMostrou-se que a SB entre os profissionais de saúde possui alta prevalência, alcançando uma taxa média de 78,4% entre seus trabalhadores. Nesse contexto, enfermeiros e médicos são os mais afetados por essa enfermidade. Destaca-se que a qualidade do atendimento aos pacientes pode ser altamente prejudicada, trazendo sérios danos a estes. Os sintomas mais experimentados pelos portadores são: exaustão física e mental, depressão, irritabilidade, entre outros. 5 CONCLUSÃOObservou-se que a SB é um grave problema para os profissionais de saúde, podendo várias complicações. Outrossim, o estresse emocional e desgastes físicos advindos dessa comorbidade interferem diretamente nos cuidados a seus pacientes. Faz-se necessário maior atenção com estes profissionais e medidas de combate aos fatores de predisposição dessa doença, a fim de dirimir as consequências descritas
Mieloma múltiplo em uma cadela de 10 anos
Background: The malignant neoplasms, in general, constitute one of the main causes of death in dogs and cats. The multiple myeloma is a neoplasm characterized by the monoclonal proliferation of plasma cells in the bone marrow, causing several systemic symptoms and it is rare in pets, representing less than 1% of the malignant neoplasms in these animals. It usually occurs in older dogs. Thus, the purpose of this report was to describe a case of multiple myeloma in a 10-year-old poodle dog, occurred in the Veterinary Hospital Unit of the State University of Ceará.Case: A 10-year-old Poodle bitch was admitted in the Veterinary Hospital Unit of the State University of Ceará presenting lump erythematosus, alopecic, soft and ulcers in the region of the digits of the left front leg, pain and lameness. The blood count evidenced normocytic and normochromic anemia, presence of rouleaux, lymphopenia and monocytopenia, and the biochemical exams have demonstrated an elevated value of alanine aminotransferase (ALT). The cytology of the nodule indicated probable diagnosis of plasma cell neoplasm and radiographic examination showed the presence of bone lysis, and therefore the patient underwent amputation of the affected limb surgery. A biopsy of the nodule indicated neoplastic proliferation, with an arrange compatible to plasmacytoma of cleaved type. A follow-up consultation was realized 30 days after surgery, and 2 new nodules appeared in the superior lip region and close to the surgery site. A new blood count indicated anemia with presence of rouleaux, thrombocytopenia, leucopenia, lymphopenia and monocytopenia, and the biochemical results showed a discrete diminution of aspartate aminotransferase(AST) and a considerable increase on the alkaline phosphatase levels. The cytology of the new nodules indicated plasmacytoma, and was realized a myelogram, that showed dysplastic marrow plasma cells, with more than 20% of plasma cells.Discussion: In the present case, the patient’s lump grew rapidly with bleeding and ulcer formation. The animal presented bone involvement, which characterizes the most suggestive sign of multiple myeloma. Justified by the stimulating factor of osteoclasts, promoting bone lysis, which can cause pathological fractures and pain. The amputation was a partial treatment to attenuates the discomfort and pain presented by the patient. The appearance of new nodules stimulated a more detailed investigation for multiple myeloma. The enzyme AST presented a discrete diminution, and ALT initially was higher than normal, but then returned to normal values. So, the elevated activity of alkaline phosphatase directed the suspects to multiple myeloma, since the activity of AST and ALT was normal, the alkaline phosphatase level was ligated to bone diseases. The rouleaux was constant at the hemograms, this is justified by the excess of immunoglobulins produced in marrow. Based on the chart presented by the patient, the bone marrow was punctured for myelogram. The symptoms displayed by the animal along with the cytological analysis, histopathological, hematological, biochemical and with myelogram indicated diagnosis of multiple myeloma. Other exams could be investigated, for example, detection of Bence Jones proteinuria, serum calcium dosage and inmunoelectroforesis for determination of the type of immunoglobulin produced by the plasma cells in the bone marrow. The definitive diagnostic was established approximately three months after the first consult, emphasizing the importance of a multiple myeloma differential diagnostic in case of plasma cell neoplasm
INFLUÊNCIA DE POLISSACARÍDEOS SULFATADOS SOBRE A MOTILIDADE E MORFOLOGIA ESPERMÁTICA PÓS DESCONGELAÇÃO DE PROCHILODUS BREVIS
This research aims to verify the influence of sulfated polysaccharides, extracted from the skin of tilapia, on the after thawing motility and morphology of P. brevis sperm. For this, 17 males were hormonally induced to reproduce, through the application of two doses of pituitary carp extract, 0.4 and 4.0mg kg-1. After the seminal collection, objective analyzes were performed and samples with motility greater than 80% were selected to form the pools. Then, the pools were frozen in solution supplemented, or not, with different concentrations of glycosaminoglycans (GAGs): 0 (control); 0.5; 1.0; 1.5; 2.0; 2.5; 3.0; 3.5; 4.0; 4.5 or 5.0mg mL-1 (total of 10 treatments). The samples were placed in 0.25 mL French straws and submitted to an equilibrium time of 10 minutes at 4 oC. Then, they were kept in the dry shipper for 15 minutes and finally stored in liquid nitrogen. After 15 days, samples were thawed in a water bath at 30 oC for 16 seconds and evaluated for sperm motility and morphology. Thus, it was observed that the increase in GAGs caused a decrease in sperm motility, however the control and the concentration of 0.5mg mL-1 presented very similar data. On the other hand, no decrease in normal sperm was observed with an increase in the concentration of GAGs. Therefore, it is concluded that the lowest concentration of GAGs is the most adequate to supplement the sperm freezing medium.Esta pesquisa tem como objetivo verificar a influência de polissacarídeos sulfatados, extraídos da pele da tilápia, na motilidade e morfologia pós-descongelamento de espermatozoides de P. brevis. Para isso, 17 machos foram induzidos hormonalmente à reprodução, através da aplicação de duas doses de extrato de pituitária de carpa, 0,4 e 4,0mg kg-1. Após a coleta seminal, análises objetivas foram realizadas e amostras com motilidade superior a 80% foram selecionadas para formar os pools. Em seguida, os pools foram congelados em solução suplementada, ou não, com diferentes concentrações de glicosaminoglicanos (GAGs): 0 (controle); 0,5; 1,0; 1,5; 2,0; 2,5; 3,0; 3,5; 4,0; 4,5 ou 5,0mg mL-1 (total de 10 tratamentos). As amostras foram colocadas em palhetas francesas de 0,25 mL e submetidas a um tempo de equilíbrio de 10 minutos a 4 oC. Em seguida, foram mantidos no dry shipper por 15 minutos e, por fim, armazenados em nitrogênio líquido. Após 15 dias, as amostras foram descongeladas em banho-maria a 30 oC por 16 segundos e avaliadas quanto à motilidade e morfologia espermática. Assim, observou-se que o aumento dos GAGs causou diminuição da motilidade espermática, porém o controle e a concentração de 0,5mg mL-1 apresentaram dados muito semelhantes. Por outro lado, não foi observada diminuição de espermatozóides normais com o aumento da concentração de GAGs. Portanto, conclui-se que a menor concentração de GAGs é a mais adequada para complementar o meio de congelamento de espermatozoides
