title: Intravenous therapy device labeling in Intensive Care Units: an integrative review

description: ABSTRACT Objectives: to synthesize the evidence on intravenous device labeling used to identify medications administered to patients in Intensive Care Units, with a view to preventing medication errors. Methods: an integrative review, in the LILACS, IBECS, Embase, MEDLINE, Scopus, Web of Science and CINAHL databases, from November to December 2021, using descriptors and selection criteria. Data were collected in 11 articles and subsequently classified, summarized and aggregated. Results: pre-designed labels, with pre-defined colors and information, help to prevent medication identification errors. There is still a lack of standardization in the practice of labeling syringes, intravenous lines, infusion pumps and saline solution bags. There are errors related to the lack of labeling devices or to their performance with incomplete information. Conclusions: device labeling is a barrier to defending the medication system safety and should be standardized.

title: Science and technology workshops as a pedagogical strategy for teaching science in elementary schools

description: Abstract This study aims to analyze the efficiency of science workshops and thus investigate associated teaching methods used with elementary school students. We evaluated the performance of the 20 participants of a science workshop during the development of 24 science projects in the second half of 2019. Their score was submitted to statistical analysis, which pointed to significant differences throughout the period. We observed that students' performance peaked between the first and the last month of the project. Workshops generate knowledge that, in a spectral and capillary way, is shared with the visitors through the speeches of each participant. Therefore, biased representations and concepts give place to new possibilities of education through research, in a way to fight denialism, which has become entrenched in our society.

title: Agro-economic benefits in radish-lettuce intercropping under optimized green manuring and planting density

description: ABSTRACT One of the biggest difficulties in the intercropping of radish-lettuce is to obtain the ideal dose of green manure and the adequate planting density for the crops. Therefore, the objective of the present work was to evaluate the agro-economic benefits of radish-lettuce intercropping under the influence of green manuring with Merremia aegyptia (hairy woodrose) and Calotropis procera (roostertree) and lettuce population densities in a semi-arid environment, in two cropping seasons. The experimental design used was randomized blocks, with treatments arranged in a 4x4 factorial scheme, with 4 replicates. The first factor in this scheme consisted of equitable biomass amounts of M. aegyptia and C. procera at doses of 20, 35, 50 and 65 t/ha on a dry basis, and the second factor of lettuce population densities of 150, 200, 250 and 300 thousand plants/ha. The production of radish and lettuce and its components, in addition to the agroeconomic indicators, system productivity index (SPI), land equivalent coefficient (LEC) and monetary equivalent ratio (MER) were evaluated. The greatest agro-economic benefits of the intercropped radish-lettuce were obtained with SPI of 15.37 t/ha, LEC of 1.27 and MER of 1.30, respectively, in the combination of 65 t/ha of M. aegyptia and C. procera biomass with the lettuce population density of 300 thousand plants/ha. The maximum commercial productivity of radish roots in the intercropping system was 8.45 t/ha in the combination of the biomass amount of 20 t/ha of M. aegyptia and C. procera and lettuce population density of 300 thousand plants/ha, while the maximum lettuce leaf productivity optimized in intercropping was 17.72 t/ha, in the combination of green manures biomass amount of 65 t/ha and population density of 300 thousand plants/ha of lettuce. The use of spontaneous species from the Caatinga biome as green manure in the radish-lettuce intercropping provides optimized agro-economic benefits in a semi-arid environment.

title: Outcomes between different validated questionnaires to assess the level of physical activity in cardiac patients adhering to a rehabilitation program

description: Abstract Introduction The International Physical Activity Ques-tionnaire (IPAQ) and Baecke inventory are commonly used in cardiovascular rehabilitation routines. Thus, it is understood that investigations on the equivalence of outcomes between these two tools may be relevant to measure the magnitude of possible reproducibility and correlations between them. Objective To compare in cardiac patients the level of physical activity obtained through the IPAQ and Baecke inventory and correlate outcomes obtained with a 6-minute walk test. Methods In total, 65 heart disease patients included in a cardiovascular rehabilitation program (40 male and 25 female) were included, with a mean age of 65.8 ± 10.5 years. The data were obtained from the application of a standardized form, containing the proposed study objects, which were the IPAQ and Baecke inventory. In addition, data regarding anthropometric measurements (body mass, height, and body mass index - BMI), waist-to-hip ratio, blood pressure, and performance in the 6-minute walk test were measured. Results The main outcomes refer to the weak association between the instruments evaluated, which showed a strong relationship only between free time physical activity (r = 1), while in the other categories and when compared to the 6-minute walk test, the verified agreement was not significant. Conclusion The questionnaires are strongly equivalent only for free time physical activity, in the other categories and when compared to the 6-minute walk test, the agreement was not significant. Thus, based on the results, implementation in clinical practice considering the use of these tools with equivalence is not recommended.

title: Use of organic substrates on the quality of watermelon seedlings

description: ABSTRACT Watermelon (Citrullus lanatus) is a succulent fruit and vine-like plant that is cultivated in Mexico and it generates employment and currency for the country. However, there is the need to research what local organic substrates can substitute peat moss as a culture medium to produce watermelon seedlings of good quality and at low cost. The objective of this study was to evaluate the physical and chemical properties of five local organic substrates as substitutes of the commercial substrate “Peat Moss”, for the production of seedlings of two watermelon cultivars, Sun Sweet and Jubilee. Five local organic substrates were studied: cacao husk, compost, vermicompost, bovine manure, coconut fiber and the commercial substrate “Peat Moss” as control. The response variables were percentage of germination, indicators of morphological quality and morphological quality indexes, stability of the clod, and relative efficiency of the local substrates. The best morphological indicators and morphological quality index of the seedlings were found with the substrates cacao husk and vermicompost, with a seedling quality similar to those obtained with the commercial substrate. Compost presented the lowest stability of the clod and relative efficiency. The substrates of cacao husk and vermicompost can substitute the commercial substrate “Peat Moss”, in addition to being easy to obtain and of low cost; so they are a viable alternative for rural farmers in the production of watermelon seedlings.

title: School alienation from the perspective of objectification theory: looking at Science teaching

description: Abstract The present theoretical study aims to present and discuss the concept of educational alienation from the perspective of Theory of Objectification (TO), a theory of teaching and learning proposed in the 1990s. Inspired by dialectical materialism and by Vygotsky's school of thought, TO seeks to break with the traditional and individualistic teaching conceptions adopted in schools. In order to explain the meaning of alienation according to TO, key concepts in this theory are discussed: knowledge, knowing, and learning. Through activity or joint labor, knowledge is set in motion and the subject is transformed, thus overcoming situations of alienation. The study contributes to thinking about educational alienation, which is still very common nowadays in schools and advocates TO as a likely break with the rationalist models of education that sustain.

title: Immunoanalysis of different antigenic preparations of Angiostrongylus cantonensis for neuroangiostrongyliasis diagnosis improvement

description: BACKGROUND Angiostrongylus cantonensis is the etiological agent of neuroangiostrongyliasis in humans, which is developed in gastropods and vertebrate species, mainly rodents. Human transmission occurs through consumption of molluscs and paratenic hosts infected with L3, and the migration of larvae to the central nervous system causes eosinophilic meningitis. Laboratory diagnosis is based on molecular and immunological tests, using young or adult females as a source of antigens. However, these tests give positive results only after several weeks of symptoms onset and also cross-reactions with others parasite infections may occur. OBJECTIVES The purpose of this work was to study different antigenic preparations of distinct evolutionary phases of A. cantonensis, in order to improve serological techniques for disease immunodiagnosis. METHODS For this purpose, antigenic fractions of different evolutionary forms were evaluated by Dot-enzyme-linked immunosorbent assay (Dot-ELISA) and Western blot using serum samples. FINDINGS All analysed fractions showed reactivity with serum samples from patients with neuroangiostrongyliasis, especially female membrane alkaline (FAM) and female soluble alkaline (FAS) fractions together with female soluble saline (FSS), improving the technique specificity. MAIN CONCLUSIONS The results point to the possibility of use of raw female antigens in association with alkaline membrane antigens extracted from adult worms to aid in diagnosis and helps initiate neuroangiostrongyliasis surveillance and control actions.

title: Correlation between musculoskeletal pain and stress levels in teachers during the remote teaching period of the COVID-19 pandemic

description: Abstract Introduction Remote teaching during the COVID-19 pandemic caused teachers to work under adverse conditions and sit in front of a computer rather than stand, which can lead to musculoskeletal pain and stress in this population. Objective To observe the prevalence of musculoskeletal pain and its correlation with stress levels in teachers during the remote teaching period of the COVID-19 pandemic. Methods A cross-sectional study carried out in elementary and high schools in the city of São José do Belmonte, Pernambuco state (PE). Sixty teachers of both sexes aged 18 years and older were evaluated. The Nordic Questionnaire of Musculoskeletal Symptoms (NQMS) was used to assess musculoskeletal pain, the Visual Analogue Scale to quantify pain intensity and the Maslach Burnout Inventory to identify symptoms of stress and burnout. Results Seventy five percent (n = 45) of the teachers reported musculoskeletal pain, with a higher prevalence in the lumbar spine 68.3% (n = 41), followed by the cervical spine 45.0% (n = 27),thoracic spine, wrists and hands, both with 41.7% (n = 25). A positive correlation was observed between the presence of musculoskeletal pain and high levels of occupational stress (p = 0.036). Conclusion A high prevalence of musculoskeletal pain was identified in teachers during the remote teaching period. The lumbar, cervical and thoracic spine, wrists and hands exhibited the highest pain prevalence. Teachers who experienced musculoskeletal pain had higher stress levels and there was a positive correlation between musculoskeletal pain intensity and high occupational stress levels.
