CARACTERIZAÇÃO EPIDEMIOLÓGICA E HISTOPATOLÓGICA DAS NEOPLASIAS MAMÁRIAS DE FELINOS EM FORTALEZA E REGIÃO METROPOLITANA

Mammary neoplasms are one of the three most neoplasms common types in female domestic cats, with an occurrence of 20 cases and a frequency of 33.90% in animals aged 10 to 12 years. Factors such as the use of hormones, pseudocyesis, obesity, and a diet rich in lipids in the young phase may be a part of the etiology of this pathologyin cats. There is a high rate of malignancy in most feline mammary tumors, most being carcinomas corresponding to 42.86% of the cases. The most common benign neoplasms are adenomas. The prognosis is reserved for most cats, and death is usually caused by clinical effects secondary to the progression of the local disease (disease located in the mammarychain) or due to metastatic spread to vital organs. Thus, the diagnosis is of extreme importance for a good prognosis. The present work aimed at the epidemiological and histopathological characterization of mammary neoplasms in felines in the city of Fortaleza and its metropolitan region, analyzing data from 59 histopathological exams of mammary tissue samples of this species.As neoplasias mamárias são um dos três tipos neoplásicos mais frequentes nas fêmeas de gatos domésticos, sendo observada a ocorrência de 20 casos e frequência de 33,90% em animais com idade de 10 a 12 anos. Fatores como a utilização de hormônios, pseudociese, obesidade e alimentação rica em lipídeos na fase jovem podem estar envolvidos na etiologia desta patologia mamária em gatas. Existe um alto índice de malignidade na maioria dos tumores mamários felinos, sendo a maior parte carcinomas com 42,86% dos casos verificados. As neoplasias benignas mais comuns são os adenomas. O prognóstico é reservado para a maioria das gatas, sendo a morte geralmente causada por efeitos clínicos secundários à progressão da doença local (doença localizada na cadeia mamária) ou devido à disseminação metastática para órgãos vitais. Desta forma, o diagnóstico é de extrema importância para um bom prognóstico. O presente trabalho teve como objetivo a caracterização epidemiológica e histopatológica das neoplasias mamárias em felinos no município de Fortaleza e região metropolitana, fazendo uma análise de dados de 59 exames histopatológicos de amostras de tecido mamário desta espécie

COCRIAÇÃO E COLABORAÇÃO: COMO FUNCIONA ESSA RELAÇÃO NO SEGMENTO DE HOSPEDAGEM

With the development of new technologies and communication networks, as well as the limitations of the traditional economic model in the face of consumer expectations, collaborative consumption has proven to be an alternative to satisfy consumption needs. This paper aims to analyze which aspects of value co-creation most influence consumers of a collaborative hosting business. The research was developed with the application of a questionnaire with 306 users of the platform, being a descriptive study and using quantitative analysis methods to obtain the results. The results showed that Transparency and Dialogue are the main factors for the co-creation of value within the segment, with women, younger and with higher incomes, tend to be more demanding in terms of co-creation tools. This study is justified as the behavioral changes of consumers emerge regarding the hosting service, where the possibility of network interaction between users and the company has generated processes of co-creation of value.Com o desenvolvimento de novas tecnologias e redes de comunicação, bem como as limitações do modelo econômico tradicional frente às expectativas dos consumidores, o consumo colaborativo tem se mostrado como uma alternativa para a satisfação das necessidades de consumo. O presente trabalho tem como objetivo analisar quais aspectos da cocriação de valor mais influenciam consumidores de um negócio colaborativo de hospedagem. A pesquisa foi desenvolvida com a aplicação de questionário com 306 usuários da plataforma, sendo um estudo descritivo e com emprego de métodos de análises quantitativas para obtenção dos resultados. Os resultados apontaram que Transparência e Diálogo são os principais fatores de cocriação de valor dentro do segmento, sendo que pessoas do sexo feminino, mais jovens e com maiores rendas tendem a ser mais exigentes quanto às ferramentas de cocriação. Este estudo justifica-se à medida que surgem alterações comportamentais dos consumidores frente ao serviço de hospedagem, onde a possibilidade de interação em rede entre usuários e empresa tem gerado processos de cocriação de valor

Neotropical freshwater fisheries : A dataset of occurrence and abundance of freshwater fishes in the Neotropics

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used.
