desafios para atuação profissional no contexto hospitalar

A conquista da saúde enquanto um direito de todos e dever do Estado é resultado do amplo debate e lutas sociais encabeçadas pelo Movimento da Reforma Sanitária Brasileira, cujos princípios e bases teóricas se aproximam do movimento de reconceituação que concebe o atual projeto ético-político do Serviço Social. O assistente social, como profissional da área da saúde, atua pautado no conceito ampliado de saúde, ao qual para além da ausência de doenças, também diz respeito a compreensão dos impactos da Determinação Social do Processo Saúde-Doença. A organização do artigo dar-se-á da seguinte forma: na primeira seção aborda-se a inserção do Serviço Social na área da saúde, visando refletir a respeito da profissão neste âmbito das políticas públicas. Na segunda seção busca-se refletir a respeito da interdisciplinaridade e seus desdobramentos. Posteriormente, os desafios da atuação profissional em um Hospital Universitário a partir da experiência das autoras e finaliza-se com as considerações finais

O ensino da Matemática na escola: Os números e sua função social

O texto trata do ensino da Matemática na Educação Básica, precisamente nos Anos Iniciais do Ensino Fundamental. O objetivo é desenvolver uma análise teórica sobre o ensino do conteúdo de Números apresentados como saberes a serem ensinados nessa etapa da Educação Básica. Trata-se de um ensaio acadêmico, produzido como proposta de avaliação do componente curricular Matemática nos Anos Iniciais do Ensino Fundamental, ofertado no oitavo semestre do curso de pedagogia da Universidade Federal do Pará, no mês de dezembro do ano de 2020. Os resultados indicam que o ensino de Números é essencial para o desenvolvimento da criança nessa fase escolar, pois esses educandos utilizam os números cotidianamente em suas relações sociais. Aponta-se para a necessidade de um ensino de Números que seja capaz de proporcionar um aprofundamento do conhecimento empírico do aluno na utilização desses e que consiga aliá-los ao saber científico proporcionado pela escola formal

Osteopatia hipertrófica secundária a osteossarcoma condroblástico extraesquelético em um cão

Background: hypertrophic osteopathy is a periosteum disturb characterized by diffuse new bone formation which leads to significant thickening and deformity of members. Secondary in nature, it usually follows large pulmonary lesions such as abscesses and neoplasms. Extraskeletal osteosarcomas are rare and extremely malignant mesenchymal neoplasms. They comprise approximately 1% of all domestic animals’ osteosarcomas and develop in the absence of a primary bone lesion. The aim of this paper was to describe a case of hypertrophic osteopathy, involving joints and upper limbs bones including ilium, secondary to a mediastinal chondroblastic osteosarcoma with pulmonary metastasis.Case: A 10-year-old spayed female mixed breed dog, weighing 9 kg, was presented with painful limbs, lameness, hind limbs swelling and a four-month history of weight loss. Radiographic examination revealed bilateral and asymmetric periosteal reactions on diaphyseal and/or epiphyseal areas of all proximal phalanges; metacarpal, metatarsal, carpal and tarsal bones; radius; ulna; tibia; fibula; humerus; femur and right ilium. An increased soft tissue radiopacity was noted on the lateral side of the right knee joint. Thoracic radiographies and ultrasonography suggested the presence of a 5-cm neoplasm or abscess in the left caudal lung lobe. At necropsy, the lobe showed a firm and solid, oval white mass measuring 5.2 x 2.9 cm. Another mass was found in the caudal mediastinum, near the diaphragm, with same color and more irregular aspect, measuring 3.3 cm of diameter. Intense periosteal new-bone formation was seen in the entire length of the four limbs bones, characterized by thickening of the bone surface and formation of irregular trabeculae perpendicular to the cortex. Significant swelling and thickening of the joint capsule was noted in the right knee. There was no microbial growth on aerobic or anaerobic cultures from the masses samples sent to culture. Histopathological examination showed areas of chondroid differentiation, osteoidtissue formation and cell morphology suggestive of chondroblastic osteosarcoma in mediastinal region, with invasion and involvement of the diaphragm and lungs. The analyzed bone fragment had large foci of tissue compaction, peritrabecular bleeding and mineralization of osteoid tissue, permeated by plasma cells and typical lymphocytes.Discussion: Although hypertrophic osteopathy is often characterized as a disease which affects the diaphysis of distal long bones, this case presented a proximal progression of the disease. There was an unusual involvement of joints and ilium, which reinforces the importance of radiographic evaluation of these regions. Further studies on the pathogenesis of the syndrome are required, as its exact mechanisms remain obscure. It is suggested that the term hypertrophic osteoarthropathy should not be consider a misnomer since joint involvement is not exclusive of human form of the disease. Mediastinal masses are important cause of hypertrophic osteopathy. However, this is the first paper the authors are aware of that reports the occurrence of hypertrophic osteopathy secondary to mediastinal osteosarcoma. Finally, although rare, extra skeletal osteosarcoma should be considered in the differential diagnosis of intrathoracic masses in dogs with hypertrophic osteopathy. Timely diagnosis of hypertrophic osteopathy, whose signs of lameness and painful limbs draw the owner’s attention, may favor the diagnosis of severe concomitant diseases

Implicações da Pandemia para a Psicologia nas Políticas Públicas

O artigo objetivou identificar e analisar desafios e potencialidades no trabalho de psicólogas(os) nas políticas públicas brasileiras na conjuntura pandêmica. É um estudo exploratório-descritivo de abordagem mista. A coleta de dados foi realizada por meio de questionário virtual com 123 psicólogas(os) que trabalhavam nas políticas públicas no país. A análise se deu a partir da extração de medidas de tendência central e pela Análise de Conteúdo temática, em um diálogo da psicologia com a tradição marxista. Os resultados apontaram para os efeitos deletérios objetivos e subjetivos do sucateamento das políticas às(aos) profissionais, bem como o tolhimento de suas práticas. Por outro lado, também apontaram algumas potencialidades que contradizem a si próprias(os) e à realidade. Fica a premência de responsabilização do Estado em fornecer melhores condições de trabalho e fortalecer as políticas públicas para o enfrentamento à pandemia, assim como a necessidade de reflexão e transformação da psicologia e sua práxis

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Induced polyploidization increases 20-hydroxyecdysone content, in vitro photoautotrophic growth, and ex vitro biomass accumulation in Pfaffia glomerata (Spreng.) Pedersen

The present study aimed to verify the effects of induced polyploidization on Pfaffia glomerata regarding its 20-hydroxyecdysone (20E) production both in vitro and under greenhouse conditions, its in vitro photoautotrophic potential, and its ex vitro biomass accumulation and photosynthetic performance. Synthetic polyploidization efficiently produced individuals with increased in vitro photoautotrophic potential and ex vitro biomass accumulation, although photosynthetic rates per leaf area did not vary between diploids and tetraploids. Among the five tetraploids tested (P28, P60, P68, P74, and P75), P28 showed significantly increased biomass both in vitro and ex vitro when compared with diploid plants, whereas the other tetraploids did not differ significantly from the diploids in terms of biomass accumulation. Although photosynthetic rates per unit leaf area remained constant among all the plants tested, P28 showed a significantly greater total leaf area, which may have resulted in an increase in net photosynthesis on a whole-plant basis. Under greenhouse conditions, the 20E content in the tetraploid P28 was 31% higher than that in diploid plants, and the final 20E mass per plant produced by P28 ex vitro was approximately twice that produced by diploid plants. Accumulation of 20E in vitro did not follow the same pattern observed among the plants ex vitro; instead, greater accumulation was observed in diploid plants. The induction of polyploidy in P. glomerata appears to be a promising strategy for producing plants with higher biomass accumulation and 20E production ex vitro, in addition to its higher in vitro photoautotrophic potential
