THE TELESCOPIC APPROACH AS A TOOL FOR GREEN CHEMISTRY. One-pot reactions have become a powerful tool for the development of sustainable protocols in organic synthesis. In particular, the telescoping of multi-step reactions, i.e., the execution of sequential reactions without isolating and purifying intermediates, reduces the number of steps while preventing waste generation. Additionally, the processes become more sustainable through time, reagents/solvents, energy and cost savings. Therefore, the aim of this work is to summarize and discuss representative one-pot telescoped strategies involving heterocyclic construction, cross-coupling and continuous-flow reactions.

ABSTRACT  Objectives:  to map the Nursing prescriptions for patients with diagnoses related to hypothermia in the intraoperative period with the activities proposed by the Nursing Interventions Classification, and to characterize the sample based on the risk factors for the development of this discomfort.  Method:  a descriptive, documentary and retrospective study, with a quantitative approach that followed three stages: cataloging of the interventions, documentary analysis, and cross-mapping. The following variables were analyzed: patient's age and gender; surgery duration; minimum, mean and maximum temperatures, and variation of the surgery room and patient temperatures; and whether or not the type of surgery involved opening a body cavity, in a sample of 138 medical charts evaluated from August to September 2019 by using a checklist composed of identification data and diagnosis components from the NANDA-International diagnoses: risk of perioperative hypothermia and hypothermia. Absolute and percentage frequency analyses, mean, standard deviation, and the R software were employed.  Results:  419 activities incorporated in 12 interventions were verified that were related to hypothermia in the corresponding taxonomy; as well as 13 Nursing care measures prescribed and five interventions mapped. The variables which reached significance were surgery duration and cavity opening.  Conclusion:  by means of cross-mapping, it can be asserted that the care measures prescribed are based on the standardized language, thus contributing to unification of the Nursing practice.
PREPARATION OF IRON/CARBON MATERIAL FROM BIODIESEL WASTE FOR APPLICATION IN THE REMOVAL OF ORGANIC CONTAMINANTS. In this work, iron/carbon-based catalysts obtained from biodiesel residues, glycerin, were prepared. The composites were prepared by thermal carbonization of the glycerin polymer, from biodiesel residues, in the presence of iron salt. The materials obtained were characterized by adsorption/desorption of N2, scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy and thermogravimetric analysis. XRD analysis have shown the presence of hematite and magnetite. The methylene blue (MB) adsorption and oxidation tests reached 99% color removal in the presence of hydrogen peroxide. The steadystate spectra confirmed the MB oxidation by the reduction of the fluorescence intensity. Besides, it has high stability, with no active phase leaching, proving a heterogeneous oxidation process.
STRATEGIES FOR THE SYNTHESIS OF LYSERGIC ACID. (+)-Lysergic acid [(+)-1] is a precursor of several substances with well-established pharmacological properties, including some drugs approved and commercialized around the world. Thus, the importance of (+)-1 as a synthetic target becomes undoubted and various strategies for the synthesis of its tetracyclic core have been reported in the literature. Therefore, in this review article we will address in chronological order the total and formal syntheses of lysergic acid (1), separating them into racemic and chiral/asymmetric syntheses. Until now, there are 24 syntheses described in the literature, namely, 11 total and 13 formal syntheses. Considering all the syntheses accomplished, 15 were planned to produce (±)-lysergic acid [(±)-1] and 9 presented routes to eventually provide (+)-lysergic acid [(+)-1]. A significant evolution regarding approaches and efficiency may be observed since the first synthesis of (±)-1 until the last asymmetric synthesis of (+)-1.
ANALYTICAL METHOD FOR DETERMINATION OF AURAMINE DYES IN ECOTOXICITY TESTS AND IN SURFACE WATERS. Dyes can be considered important environmental contaminants. Auramine dyes, known commercially as Solvent Yellow 34 and Basic Yellow 2, are used in several industrial products, including textile and paper. In this study, an analytical method was developed and validated using Liquid-Liquid Extraction and High-Performance Liquid Chromatography coupled to Diode Array Detector (LLE and HPLC-DAD) to determine the exposure concentrations in the ecotoxicological tests with auramine dyes, increasing the results reliability about the hazard of these compounds. The method was also used to monitor auramine dyes in surface water samples, in a region considered one of the most critical regions for dyes contamination in Brazil. The results showed no risk for the aquatic organisms considering the analyzed samples. The method using simple instrumentation showed the results of selectivity, linearity (R2> 0.99), precision (CV: 5.6-29%) and accuracy (recovery: 82-90%) considered satisfactory for the two purposes with Instrumental LOQ of the 12 µg L-1; and the Method LOQ of the 12 ng L-1;. The results indicated that the proposed method was effective and practical for the auramine determination in environmental levels and will be an important tool to verify the potential risk of auramine dyes in future studies.

DETECTION AND QUANTIFICATION OF SILVER NANOPARTICLES BY spICP-MS. The growing interest in nanotechnology has led to an increase in the production and application of nanoparticles worldwide. Due to the unique functional properties of nanoparticles, these materials are being used by many industries, including the agricultural and food sectors. Among the commercially available nanomaterials, it is possible to highlight those produced with silver nanoparticles. One of the most promising techniques for the analysis of metallic nanoparticles is the Inductively coupled plasma mass spectrometry (ICP-MS) performed in single particle mode (spICP-MS). However, the use of the technique in the detection and measurement of nanoparticles requires that the equipment be operated differently than when used to analyze dissolved metal solutions. Thus, this article presents the use of the spICP-MS technique for the measurement and quantification of nanoparticles, as well as their validation. The method proved to be adequate for the purpose, presenting a satisfactory result for the selectivity test and recovery of 83.7 (40 nm) and 77.6% (80 nm). The detection limits, determined for the most frequent size, dissolved silver concentration and particle concentration, were 17.5 nm, 0.736 ng mL-1;, 146 particles mL-1;, respectively. Thus, the results obtained indicated the possibility of using the technique to determine the size and concentration of silver nanoparticles.

Método: Pesquisa qualitativa, fundamentada no Interacionismo Simbólico e conduzida conforme a técnica metodológica da Teoria fundamentada nos dados. Participaram do estudo 12 mulheres com diagnóstico de câncer gestacional e 19 familiares. A coleta dos dados ocorreu de março de 2018 a março de 2019, por formulário de identificação e entrevista em profundidade. A análise seguiu etapas da codificação substantiva aberta.  Resultados: Dados foram organizados em duas categorias de análise: Sendo surpreendida pela descoberta do câncer na gestação, que revela o curso de vivenciar a gestação e ter o diagnóstico de câncer; e Sofrendo pelas repercussões do câncer na gestação e no nascimento, que descreve as repercussões do adoecimento na vivência da gestação.  Conclusão: O câncer gestacional foi diagnosticado em mulheres jovens a partir de sinais e sintomas que foram confundidos com os próprios da gestação e do pós-parto. O adoecimento foi permeado por ansiedade, impotência e medo, repercutindo na forma de vivenciar a maternidade, já que afastou da gestação planejada e impôs rotinas que distanciaram daquelas vividas em uma gestação de risco habitual.

ABSTRACT  Objective: To investigate how the diagnosis of cancer during pregnancy occurred and assess its repercussions on the family experience of maternity.  Method: Qualitative research, based on Symbolic Interactionism and conducted according to the Grounded Theory method. Twelve women diagnosed with cancer during pregnancy and 19 of their family members participated in the study. Data was collected from March 2018 to March 2019, using an identification form and an in-depth interview. The analysis followed the stages of open substantive coding.  Results: Data were organized into two categories of analysis: Being surprised by the discovery of cancer during pregnancy, which reveals the course of experiencing pregnancy and being diagnosed with cancer, Suffering from the repercussions of cancer on pregnancy and birth, which describes the repercussions of illness in the experience of pregnancy.  Conclusion: Cancer during pregnancy was diagnosed in young women based on signs and symptoms that were confused with those of pregnancy and postpartum. The illness brought anxiety, impotence, fear and affected the experience of maternity, as it prevented women from having their pregnancy as planned and required routines different from those of low-risk pregnancies.
A PROPOSAL FOR ANALYZING CHEMISTRY ISSUES AT ENADE ACCORDING TO THE COGNITIVE LEVEL OF DIFFICULTY. This article aims to present an analysis of the ENADE-Chemistry exam using a taxonomy based on the cognitive operations mobilized to solve the chemistry issues here called as Cognitive Level of Difficulty. In addition to identifying contents in the area of knowledge, skills and competences. All questions from the exams of the years 2011, 2014 and 2017 were analyzed; selected the statistical data present on the reports issued by INEP for four higher-educational institutions (UFRN, UTFPR, UFU and UFAM) and the percentages of the distractors indicated. These data were organized in an excel spreadsheet (database) that helped the comparisons of different variables. As a result, we observed discrepancies when comparing the variables of the ease index and the cognitive level of difficulty for the questions that addressed general chemistry concepts. For example, issues considered very difficult in the easiness rating, but which required low order thinking skills and reciprocally. We consider the proposed taxonomy of analysis of cognitive operations and the database is a tool that can contribute to their courses structure. Furthermore, the proposal can be extended to other areas.
RESUMO O estudo das causas do desperdício alimentar e das potenciais intervenções para a sua minimização está entre as preocupações centrais daqueles que trabalham com alimentos. A alimentação na educação, que inclui os refeitórios das universidades, está entre os setores que merecem atenção, uma vez que quantidades significativas de alimentos são desperdiçadas pelos consumidores. Entretanto, ainda há uma escassez de estudos que abordem o problema. Este estudo teve como objetivo geral investigar o desperdício de alimentos em um refeitório de uma universidade brasileira, bem como a percepção dos consumidores em relação às refeições servidas. Por meio de um questionário, foi possível investigar quais as principais percepções dos consumidores, e o que poderia estar por trás da geração do desperdício. Utilizou-se a correlação de Spearman a fim de verificar a correlação entre o desperdício alimentar e a percepção dos consumidores sobre as razões por trás da geração do desperdício. Verificou-se um desperdício médio de 68 g/consumidor. Além disso, foi observado que os consumidores que colocavam os alimentos em bandejas desperdiçavam mais alimentos do que aqueles que optavam por comer em pratos. As informações coletadas foram utilizadas para propor potenciais intervenções voltadas à redução do desperdício de alimentos em refeitórios universitários.

ABSTRACT Studying the causes of food waste and potential interventions for minimizing it is one of the main concerns of those who work with food on all levels. Food in the education sector, which includes dining halls in higher education institutions, is among the sectors that deserve attention, since its consumers generate significant amounts of food waste. There is still a lack of studies, however, addressing the problem of food waste in dining halls. The general objective of this study is to investigate food waste in a Brazilian university dining hall, and consumer perceptions of the meals. By means of a questionnaire, it was possible to investigate the main perceptions of consumers, and what might be behind the waste generated. Spearman’s correlation was performed in order to verify the correlation between consumer food waste and consumer perceptions as to the reasons behind the food waste that is generated. It was found that average waste was 68g/consumer. It was also observed that consumers who placed their food in trays wasted more food than those who chose to eat from a dish. All the collected information was used to propose potential interventions to reduce food waste in university dining halls.
Resumo A agenesia de veia cava inferior é descrita em menos de 1% da população, de ocorrência rara e devido a alterações embrionárias. Sua correlação com a trombose venosa profunda certamente é subestimada, visto que tal alteração é de difícil detecção pela ultrassonografia. O objetivo deste artigo foi relatar o caso de uma paciente de 41 anos com dor e edema até a raiz de coxa direita após cirurgia plástica. Foi realizado dúplex venoso de membros inferiores e evidenciada trombose venosa profunda ilíaco-femoro-poplíteo e distal bilateralmente. Solicitado angiotomografia venosa devido a não visualização de veia cava inferior no ultrassom, evidenciando trombose de plexo lombar direito e segmento ilíaco-femoral bilateral, além de agenesia de segmento infra-hepático de veia cava inferior, com ectasia e tortuosidade compensatória de veias paravertebrais, sistema ázigos e hemiázigos, com varizes pélvicas bilateralmente. Foi realizada anticoagulação sistêmica e oral, com boa evolução clínica.

Abstract Agenesis of the inferior vena cava (IVC) has been described in less than 1% of the population; a rare occurrence caused by embryonic abnormalities. Its correlation with deep vein thrombosis (DVT) is certainly underestimated, since this change is hard to detect using ultrasound. The aim of the article is to report the case of a 41-year-old female patient with pain and edema up to the top of the right thigh after plastic surgery. Bilateral venous duplex ultrasound revealed bilateral DVT involving iliac-femoral-popliteal and distal segments. Venous angiotomography was requested because the IVC was not visible on ultrasound, revealing thrombosis of the right lumbar plexus and iliofemoral segment bilaterally and agenesis of the infrahepatic segment of the inferior vena cava, with ectasia and compensatory tortuosity of paravertebral veins and the azygos-hemiazygos system, and bilateral pelvic varices. Systemic and oral anticoagulation were administered, with a satisfactory clinical response.
ESSENTIAL AND VEGETABLE OILS: RAW MATERIALS FOR THE MANUFACTURE OF BIOPRODUCTS IN CLASSES IN EXPERIMENTAL ORGANIC CHEMISTRY. A schedule was prepared for three undergraduate classes for the discipline of experimental organic chemistry for obtaining bioproducts. As natural raw materials, lavender flowers and cinnamon peels were used to obtain hydrolates and essential oils (Class 1), coconut and avocado pulp to obtain vegetable oils and annatto seeds to obtain a natural dye (Class 2). Cosmetic bioproducts (Class 3), body emulsions similar to those found on the market, were obtained from the mixture of essential and vegetable oils and the addition of natural dye. The raw materials obtained can also be used in other classes of the discipline, complying with the principles of Green Chemistry. Essential oils, for example, can be used as samples for Thin Layer Chromatography (TLC) classes and vegetable oils for the production of biodiesel.
