Generalidades sobre o quadro clínico da Rinossinusite: uma revisão narrativa de literatura: Generalities about the clinical picture of Rhinosinusitis: a narrative literature reviewv
A rinossinusite é um processo inflamatório da mucosa dos seios paranasais e da cavidade nasal. O sistema nasossinusal é responsável pelo balanço adequado entre a fabricação e o clearence de muco nas cavidades paranasais. A fisiologia deste é de vital importância para a proteção das vias aéreas superiores. No advém, determinados fatores podem acarretar um desbalanço nesse complexo, consequentemente um processo inflamatório. Qualquer fator que altere a drenagem, seja por obstrução, maior produção ou espessamento do muco, como processo infecciosos ou alérgicos, haverá uma impactação de secreções e a facilitação de colonização bacteriana, dando início ao processo infeccioso. A identificação da inflamação do nariz e seios paranasais é basicamente clínica. A suspeição desta ocorre através da manifestação de dois ou mais sintomatologias. As quais são o bloqueio ou obstrução nasal, a descarga nasal, pressão ou dor facial e redução ou perda do olfato. De modo geral, é essencial à prevenção básica das rinossinusites agudas é barrar a infecção viral. O suporte inclui medidas gerais de higiene, alimentação e hidratação, imunização para o combate de vírus respiratórios , administração de fármacos para turbinar o sistema imune se necessário
Incidência da síndrome pré-menstrual na prática de esportes: aspectos atuais: Incidence of pre-menstrual syndrome in sports: current aspects
A síndrome pré-menstrual (SPM) é uma constelação complexa de alterações de humor, comportamentais e físicas que se limitam à fase pré-menstrual. Esses sintomas se recuperam dentro de alguns dias após o início da menstruação. Assim, o objetivo desse estudo é demonstrar a incidência da síndrome pré-menstrual na prática de esportes a partir de uma revisão integrativa sobre o tema. Para isso, foi realizado uma revisão integrativa sobre o tema, onde foi considerado textos publicados desde 2010, em inglês e português e que estejam disponíveis para leitura, no PUBMED, LILACs e Scielo. Esta revisão sistemática fornece algum suporte adicional para diretrizes clínicas que recomendam o exercício como um tratamento eficaz para a TPM. As análises secundárias realizadas também fornecem novas evidências de que o exercício pode ser útil no alívio de sintomas psicológicos, físicos e comportamentais específicos associados à TPM, além de auxiliar no gerenciamento do perfil global de sintomas
Perception of undergraduate students of a Brazilian University about the Biochemistry course
Biochemistry is an essential science that deals with the chemical bases of life, being an important discipline for several areas. Thus, the objective of this work was to evaluate the opinion of students about the Biochemistry course. An instrument, involving questions about the discipline, the professors, the monitors, and a self-evaluation was applied to 231 students from 12 undergraduate courses, divided into 3 areas of knowledge: Natural, Health and Rural Sciences. The majority of the students answered that they consider Biochemistry an important discipline, but they presented a reasonable comprehension of the contents, probably by a lack of chemical skills. The students consider the credit hour of the discipline sufficient but badly used. They said that the Professor performance is reasonable to good, and miss a correlation between the class and the professional acting, especially in the Rural Science. This study showed that the Biochemistry classes need to be rethought for the areas of action of each course. In addition, the students' basic pre-knowledge should be improved

Departamento de Clínica Médica. Belém, PA, Brasil.O lúpus eritematoso sistêmico (LES) é uma doença autoimune crônica, cujo desenvolvimento pode estar associado
à infecção por vírus, como o vírus Epstein-Barr (EBV), parvovírus B19 e vírus linfotrópico de células T humanas
(HTLV). Durante o período de junho a setembro de 2014, foi realizado um estudo transversal, incluindo 85
pacientes oriundos do Hospital Jean Bitar, na Cidade de Belém, Estado do Pará, Brasil. Foi realizada a pesquisa de
anticorpos específicos contra os agentes virais estudados, assim como pesquisa da presença do genoma para EBV e
HTLV. Foram avaliadas também variáveis clínicas e epidemiológicas. A maioria dos pacientes eram mulheres, tinham
média de idade de 30 anos e se declararam brancos. Para EBV, detectou-se positividade de 37,6% para IgM,
98,8% para IgG e 2,4% por qPCR, com quantificações de 85.028 e 298 cópias do genoma/mL de plasma. Para
B19, a positividade para IgM foi 0% e para IgG 67,1%. Não houve detecção sorológica ou por qPCR de HTLV. Foi
verificada relação estatisticamente significante entre a positividade para IgM anti-EBV e pacientes mais jovens. Esse
achado pode estar relacionado com a maior eficiência na produção dessa imunoglobulina nas infecções primárias
agudas, que ocorrem geralmente em indivíduos infantes ou adultos jovens. Adicionalmente, o resultado de IgG
anti-B19 foi associado à idade avançada dos pacientes, provavelmente por um maior tempo de exposição ao vírus
aliado à persistência desse marcador após o contato. A presença dos marcadores não esteve associada às variáveis
clínicas e epidemiológicas. Entretanto, o percentual de positividade para o marcador de infecção aguda por EBV
pode sugerir um envolvimento do vírus com o LES.Systemic lupus erythematosus (SLE) is a chronic autoimmune disease whose development may be associated with
viral infections, such as Epstein-Barr virus (EBV), parvovirus B19, and human T-cell lymphotropic virus (HTLV). A
cross-sectional study was performed between June and September 2014 involving 85 patients from the Hospital Jean
Bitar, located in Belém, Pará State, Brazil. A survey of specific antibodies against the studied viral agents was conducted,
in addition to a survey of the EBV and HTLV genomes. Clinical and epidemiologic variables were also evaluated. Most
patients were female, approximately 30 years old, and declared themselves as Caucasians. The following positive
results were detected for EBV: IgM = 37.6%, IgG = 98.8%, and qPCR = 2.4%, with 85,028 and 298 copies of
the genome per milliliter of plasma. Positive results for B19 were: IgM = 0%, IgG = 67.1%. Serological or qPCR
detection did not reveal HTLV. A significant statistical correlation was observed between anti-EBV IgM antibodies and
younger patients. These findings may be related to the highly efficient production of this immunoglobulin during acute
primary infections, which frequently occurs in children and young adults. Furthermore, the results for anti-B19 IgG
were associated with the patients' advanced age, resulting from the longer exposure period to the virus combined with
this marker's persistence after exposure. Presence of the marker was not associated with clinical and epidemiological
variables. However, the percentage of cases of acute infection by the EBV marker suggests an association with SLE
Em busca de um horizonte : narrativas sobre educação, artes e resistência
"APRESENTAÇÃO -
Os textos reunidos no livro Em busca de um Horizonte: narrativas sobre educação, arte
e resistência foram inspirados nos debates realizados durante o evento VI Simpósio Internacional
Horizontes Humanos, que aconteceu na Faculdade de Educação da Universidade
de Brasília, em 2018. O livro está dividido em quatro partes: Resistências cotidianas
para além da utopia, Demasiado humano: as diferentes linguagens artísticas e culturais,
A educação como um horizonte, Educação ambiental e ancestralidade: para continuar
caminhando. Apesar da divisão em seções (sempre arbitrária), as produções - bastante
diversas nas temáticas, metodologias e referenciais teóricos adotados – compartilham
um alinhamento ao adotar um posicionamento político em defesa da diversidade, dos
direitos humanos, da ancestralidade, do meio ambiente, da educação com valores democráticos,
dos saberes populares e das diferentes linguagens artísticas. Assim, o livro
se apresenta como um convite à resistência em tempos atrozes.

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. There are no copyright restrictions on the data, and please cite this data paper when using the data in publications
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. We also request that users inform us of how they intend to use the data
NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics
Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans data set.

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics
Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions. Please cite this data paper when using the data in publications. We also request that researchers and teachers inform us on how they are using the data
Brazilian Flora 2020: Leveraging the power of a collaborative scientific network
International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
