    Seed companies use vigor tests in their internal seed quality control procedures. Therefore, it is necessary to choose effective methods to obtain quick responses for making decisions related to the handling, disposal and marketing of seed lots. Thus, the objective of this work was to adapt a methodology for the accelerated aging test in soybean seeds. Sixty-nine lots were used and the experimental design used was completely randomized, with four replications. For the initial characterization of the lots, water content was determined, germination test and field emergence. The soybean seed lots selected based on the initial characterization, were submitted to the standard accelerated aging methodology and twenty-one adapted methodologies. After the physiological characterization of the 69 lots, 24 lots with similar germination with different levels of vigor were selected. For adapted methodologies that used only distilled water inside the gerbox box, there was an increase in the water content of the seeds of all analyzed lots. However, all methodologies with the use of saline solution had a lower water content. The adapted methodologies N (pre-treatment in forced air oven at 35-40ºC for two hours, BOD 42ºC for 24 hours, using saline) and S (pre-treatment in forced air oven at 35-40ºC for two hours, BOD 45ºC for 12 hours, with the use of distilled water) are the most suitable for use in the accelerated aging test for soybean crops, as they present relevant results in a shorter evaluation period.As empresas de sementes utilizam testes de vigor em seus procedimentos internos de controle de qualidade das sementes. Por isso, é necessário escolher métodos eficazes para obter respostas rápidas para a tomada de decisões relacionadas ao manuseio, descarte e comercialização de lotes de sementes. Assim o objetivo deste trabalho foi adaptar uma metodologia para o teste de envelhecimento acelerado em sementes de soja. Foram utilizados sessenta e nove lotes em um delineamento experimental inteiramente casualizado, com quatro repetições. Para a caracterização inicial dos lotes foi realizado a determinação do teor de água, teste de germinação e emergência a campo. Os lotes de sementes de soja selecionados com base na caracterização inicial, foram submetidos a metodologia padrão do envelhecimento acelerado e vinte e uma metodologias adaptadas. Após a caracterização fisiológica dos 69 lotes, foram selecionados 24 lotes com germinação semelhante com diferentes níveis de vigor. Para as metodologias adapatadas e que foram utilizadas apenas água destilada no interiro da caixinha de gerbox, ocorreu um aumento no teor de água das sementes de todos lotes analisados, entretanto,  todas as metodologias com o uso de solução salina, apresentaram um teor de água menor. As metodologias adaptadas N (pré-tratamento em estufa de ar forçado a 35-40ºC por duas horas, BOD 42ºC por 24 horas, com o uso de solução salina) e S (pré-tratamento em estufa de ar forçado a 35-40ºC por duas horas, BOD 45ºC por 12 horas, com o uso de água destilada) são as mais indicadas para o uso no teste de envelhecimento acelerado para a cultura da soja, por apresentarem resultados relevantes em um menor período de avaliação

    Os distúrbios hidroeletrolíticos são eventos comumente observados na prática médica, inclusive em situações de emergência, podendo representar risco de vida ou possibilidade de sequelas para o paciente a depender da magnitude do caso. Independentemente da etiologia, a desidratação tem sua importância definida pela intensidade das perdas líquidas e pela proporção de perdas salinas em relação à perda de água. Isto evidencia a importância de se avaliar corretamente o quadro para se desenvolver um tratamento adequado. Este estudo tem como objetivo explorar o tema das repercussões e manejo de distúrbios hidroeletrolíticos nos pacientes graves a partir de uma revisão sistemática com meta análise com o emprego das palavras chave “unidade de terapia intensiva”, “gerenciamento hidroeletrolítico”, “distúrbios hidroeletrolíticos” e “controle de líquidos e eletrólitos” nos bancos de dados PubMed, BVS, Lilacs, Medline e Scielo objetivando acessar artigos publicados entre 2015 e 2022. A equipe de enfermagem está diretamente responsável pelo manejo de pacientes de alta complexidade, o que pode envolver casos que exigem o gerenciamento hidroeletrolítico, isto requer um conhecimento aprofundado dos mecanismos envolvidos no metabolismo da água e dos eletrólitos. O monitoramento diário da função renal pela equipe de enfermagem é um cuidado importante para se evitar o quadro de insuficiência renal aguda

    Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

    Apresenta-se uma revisão integrativa sobre estudos que abordam as relações entre profissionais de saúde e usuários durante as práticas em saúde. Objetivou-se identificar os aspectos pesquisados no cotidiano dos serviços acerca dessas relações. A coleta foi realizada nas bases Lilacs e Pubmed segundo os descritores: acolhimento; relações profissional-família; relações profissional-paciente; humanização da assistência; e a palavra 'vínculo' associada ao descritor Sistema Único de Saúde. Selecionaram-se 290 estudos publicados entre 1990 e 2010. Por meio da análise temática, foram criados cinco núcleos de sentido: a relevância da confiança na relação profissional-usuário; sentimentos e sentidos na prática do cuidado; a importância da comunicação nos serviços de saúde; modo de organização das práticas em saúde; e (des)colonialismo. Identificou-se que as relações estabelecidas nas práticas de saúde têm uma dimensão transformadora. No entanto, permanece o desafio de humanizar os serviços de saúde. A enfermagem se destaca na produção do conhecimento nessa temática.<br>This article presents an integrative review about studies that address the relationships between health professionals and users in health care practices. It aimed to identify aspects that were researched on the daily life of the services concerning such relationships. Data were collected from the Lilacs and Pubmed databases based on these descriptors: user embracement; professionalfamily relations; professionalpatient relations; humanization of the care; and the bonding word associated to the Single Health System descriptor. Two hundred and ninety studies, published from 1990 to 2010, were selected. Through thematic analyses, five meaning cores were created: the relevance of the confidence in the professionaluser relationship; feelings and senses in the health care practice; the importance of communications in health care services; ways to organize health care practices and (de)colonialism. It was found that relationships established in health care practices have a transformative dimension. However, the challenge to humanize health care services remains. Nursing stands out in the production of knowledge on such theme

    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.
