    Abstract Introduction: Physiologically based pharmacokinetic (PBPK) modeling is a computational approach that simulates the anatomical structure of the studied species and presents the organs and tissues as compartments interconnected by arterial and venous blood flows.
    Aim: The aim of this systematic review was to analyze the published articles focused on the development of PBPK models for interspecies extrapolation in the disposition of drugs and health risk assessment, presenting to this modeling an alternative to reduce the use of animals.
    Methods: For this purpose, a systematic search was performed in PubMed using the following search terms: "PBPK" and "Interspecies extrapolation". The revision was performed according to PRISMA guidelines.
    Results: In the analysis of the articles, it was found that rats and mice are the most commonly used animal models in the PBPK models; however, most of the physiological and physicochemical information used in the reviewed studies were obtained from previous publications. Additionally, most of the PBPK models were developed to extrapolate pharmacokinetic parameters to humans and the main application of the models was for toxicity testing.
    Conclusion: PBPK modeling is an alternative that allows the integration of in vitro and in silico data as well as parameters reported in the literature to predict the pharmacokinetics of chemical substances, reducing in large quantity the use of animals that are required in traditional studies.

    Abstract Purpose: To identify the prevalence of the nursing diagnosis of compromised end-of-life syndrome in patients in end-of-life care.
    Methods: This is a clinical validation based on a cross-sectional epidemiological clinical study conducted at the National Cancer Institute in Rio de Janeiro, Brazil. The defining characteristics of a syndrome diagnosis were identified, defined as a "subset of nursing diagnoses," using sensitivity and specificity measures through the application of latent class statistical methods.
    Findings: The statistical results revealed seven nursing diagnoses characterizing the syndrome: imbalanced nutrition: less than body requirements, nausea, anxiety, ineffective breathing pattern, disturbed sleep pattern, ineffective thermoregulation, and fatigue. Compromised end-of-life syndrome was present in 76% of the sample.
    Conclusion: The study demonstrated the presence of compromised end-of-life syndrome in most end-of-life patients from the sample.
    Implications for nursing practice: Recognizing the presence of the syndrome diagnosis enables nurses to have efficient and effective clinical reasoning for implementing the nursing process in palliative care. CAAE Number: 85415618.0.3001.5274.

    Abstract Biosensors with nanomaterials and enzymes detect and quantify specific targets in samples, converting recognition into measurable signals. The study explores the intrinsic synergy between these elements for detecting and quantifying particular targets in biological and environmental samples, with results demonstrated through bibliometric analysis and a comprehensive review of enzyme-based biosensors. Using WoS, 57,331 articles were analyzed and refined to 880. Key journals, countries, institutions, and relevant authors were identified. The main areas highlighted the multidisciplinary nature of the field, and critical keywords identified five thematic clusters, revealing the primary nanoparticles used (CNTs, graphene, AuNPs), major application fields, basic application themes, and niche topics such as sensitive detection, peroxidase activity, and quantum dot utilization. The biosensor overview covered nanomaterials and their primary applications, addressing recent advances and inherent challenges. Patent analysis emphasized the U.S. leadership in the industrial sector, contrasting with China's academic prominence. Future studies should focus on enhancing biosensor portability and analysis speed, with challenges encompassing efficient integration with recent technologies and improving stability and reproducibility in the nanomaterial-enzyme interaction.

    Abstract Atmospheric nitrogen fixation carried out by microorganisms has environmental and industrial importance, related to the increase of soil fertility and productivity. The present work proposes the development of a new high precision system that allows the recognition of amino acid sequences of the nitrogenase enzyme (NifH) as a promising way to improve the identification of diazotrophic bacteria. For this purpose, a database obtained from UniProt built a processed dataset formed by a set of 4911 and 4782 amino acid sequences of the NifH and non-NifH proteins respectively. Subsequently, the feature extraction was developed using two methodologies: (i) k-mers counting and (ii) embedding layers to obtain numerical vectors of the amino acid chains. Afterward, for the embedding layer, the data was crossed by an external trainable convolutional layer, which received a uniform matrix and applied convolution using filters to obtain the feature maps of the model. Finally, a deep neural network was used as the primary model to classify the amino acid sequences as NifH protein or not. Performance evaluation experiments were carried out, and the results revealed an accuracy of 96.4%, a sensitivity of 95.2%, and a specificity of 96.7%. Therefore, an amino acid sequence-based feature extraction method that uses a neural network to detect N-fixing organisms is proposed and implemented.

    Abstract Introdução: As reações adversas a medicamentos (RAM’s) são consideradas um grave problema de saúde pública, sendo responsáveis pelo aumento da morbimortalidade e dos custos com a saúde. Objetivo: Conhecer o perfil de ocorrência e descrever as características dos casos de RAM’s notificadas em um hospital sentinela de Minas Gerais. Método: Estudo observacional, descritivo e transversal, que utilizou como fonte a planilha de notificações de suspeita de RAM’s da gerência de risco do hospital no período de janeiro de 2015 a dezembro de 2019. Resultados: Foram analisadas 255 notificações, sendo a maioria provenientes de busca ativa (69,4%), envolvendo 269 medicamentos e 328 episódios de RAM’s. O setor com maior número de notificações foi a Clínica Médica (43,9%). A faixa etária dos pacientes mais acometidos situou-se entre 19-59 anos (54,5%), predominando o sexo masculino (50,6%) e a raça branca (54,1%). Grande parte das RAM’s manifestou-se através de distúrbios no sistema tegumentar (36,3%), com gravidade leve (63,9%), provindas principalmente do uso de anti-infecciosos sistêmicos (44,6%). Conclusão: Conclui-se que as notificações de RAM’s são recorrentes no âmbito hospitalar e o conhecimento destas permite traçar seu perfil clínico, auxiliando na prevenção das mesmas e contribuindo para maior segurança do paciente.
