Sugarcane is a commercially important species for sugar and biofuel production and because of the high demand for plant material in planting, new means of propagation are being developed and require improvements. Therefore, the objective of this study was to evaluate the effect of different concentrations of indole-butyric acid (IBA) applied in the form of talc on the initial growth and emergence of sugarcane mini-cuttings used for the system of pre-sprouted plantlets (PSP). Mini-cuttings were treated with concentrations of 0, 500, 1000, 1500 and 2000 mg kg-1 of IBA in the form of talc and evaluated for emergence and initial growth. There was no difference between IBA concentrations for the physiological, biometric and dry mass variables analyzed. The sugarcane plantlets formed had emergence above 89%, functional photosynthetic apparatus, 4.4 leaves on average, stem diameter of 11.90 mm, shoot length of 12.18 cm, leaf area of 108.81 cm² and root area of 142.17 cm². Shoot dry mass and root dry mass were equal to 2.27 and 1.20 grams, respectively. Thus, concentrations of up to 2000 mg kg-1 of IBA applied in the form of talc in sugarcane mini-cuttings had no effect on rooting and initial growth of plantlets.

Beans are one of the most produced foods in the entire national territory, with an intense search for productive cultivars with good culinary characteristics. In view of the growing concern of consumers with the diet, the positive implications of functional foods for health and the benefits of beans for the organism, the objective of this study was to verify the content of bioactive compounds and the antioxidant capacity of eight common bean cultivars. cowpea, before and after cooking, as well as in their respective broths. From the samples, the concentrations of ascorbic acid, chlorophyll, carotenoids, anthocyanins, flavonoids, phenolic compounds and antioxidant capacity were determined, and the data obtained were compared using the Tukey test at the 5% probability level. As a result, it was observed that the cultivar Costela de Vaca had the highest concentrations of chlorophyll and carotenoids before and after cooking. There was an increase in the concentration of flavonoids and a reduction in the ascorbic acid content after cooking in all evaluated cultivars. The cultivar BRS Marataoã showed the highest concentration of phenolic compounds in the raw grain and, consequently, the highest antioxidant capacity, however with reduced activity after cooking. For cooking broths, BRS Marataoã and Costela de Vaca were the ones that had the greatest capacity to fight free radicals. Although cooking caused changes in the concentrations of bioactive compounds, the cultivars remained with important functional characteristics, recommending the consumption of green cowpea with cooking broth for greater retention of compounds with antioxidant properties.

Practical activities are important resources for science teaching, however, the scarcity of biological materials prevents their widespread use in Basic Education. In this context, this study aims to analyze the contribution of the production of a zoological collection to the process of teaching and learning about arthropods in a class with 16 students from the 7th year of a public school in the interior of Rio Grande do Sul. It is a laboratory research established through an initial theoretical-practical approach to the content of arthropods, with subsequent collective production of a zoological collection of arthropods (covering collection, assembly and conservation processes). The analysis of the results occurred through observation and recording in a field diary. We obtained 16 specimens of the subphylum Chelicerata, seven specimens of Myriapoda, two specimens of Crustacea and 38 specimens of Hexapoda. The collection proved to be an efficient material for the teaching process on arthropods, since such a tool is low cost and has the potential to attract students' interest and curiosity. In addition, it brings students closer to the content developed in the classroom, helping to understand morphological, anatomical, physiological and ecological aspects. In addition, it is concluded that it allowed to signal differences and clarify myths, contributing to a meaningful learning and to be used in future classes.

The tobacco can generate chemical addiction to its users, especially in vulnerable groups such as university students which upon entering university may develop conflicts of principles employed by family education, besides the need for social insertion and the influence of friends The purpose of this study is the analysis of the biopsychosocial aspects related to tobacco consumption among college students. To reach this objective, an integrative literature review was carried out using the SciELO Brasil, SciELO Saúde Pública, SciElo, OneFile and Scopus databases. Using the terms "aspectos biopsicossociais", "consumo de produtos derivados do tabaco", "consumo de tabaco", "tabagismo", "estudante universitário". The inclusion and exclusion criteria were observed on 3.105 articles in which ten of them made up the final sample. It was observed that college students are vulnerable to tobacco use due to factors such as social influence, psychological pressure, and anxious situations generated by the university. Tobacco consumption by young people is marked by the use of other drugs, usually alcohol, causing harm to health. It is concluded that health students are more active in this consumption, despite knowing the risks caused by tobacco.

The aim of this study was to assess the functional capacity of institutionalized older people and to verify which sociodemographic, health factors and oral health were related to the worse ability to perform daily activities. It was a cross-sectional study conducted with 512 institutionalized elderly people. Sociodemographic profile; general health and oral health conditions were evaluated. Functional capacity was assessed by Barthel Index. A high prevalence of functional dependent elderly was found (47.1%). A lower functional capacity was associated with female (p=0.006); higher education (p=0.009); older elderly (p<0.045); decision to institutionalize by others (p=0.011); affected cognitive state (p<0.001); reduced mobility (p<0.001), less autonomy for self-care in oral health and worse oral health. Institutionalized elderly has low functional capacity that is related to several aspects of their lives.

The characterization of plant species with beekeeping potential, which are present in beekeeping production systems, can bring many advantages. Among the benefits, the choice of the beehives implantation place according to the availability of floral resources in the agroecosystems, allowing to increase the productivity and the quality of honeys and other products from the bees, are highlighted. In this sense, the aim of this work was to collect flowering plant species, which were visited by bees close to beehive monitoring systems, in six agroecological zones of the Santa Catarina state, Brazil. The taxonomic and geographical identification of these species were also carried out. For each sample, its location was registered in order to estimate the route distance taken by the bees, since the location of the hive was fixed. Of the 157 identified samples, 81 species and 68 genera were found in 33 families, with Asteraceae and Fabaceae being predominant. For Asteraceae, the most reported genera were Baccharis, Tithonia, Senecio, and Sphagneticola, while for Fabaceae, the most reported genus was Trifolium. Species such as Sphagneticola trilobata (Asteraceae), Trifolium repens, T. pratense, Cajanus cajan, Vicia sp. (all Fabaceae), Verbena litoralis, Lantana undulata (both Verbenaceae), Raphanus sativus (Brassicaceae), and Clidemia hirta (Melastomataceae) can be considered interesting from an apicultural point of view, as they remained with flowers between the first and last day of sample collection in some regions (~ 60 days). Although the distances between the plants and the beehives have high variability (8 to 1154 m), the distances generally do not exceed 750 m.

The aim of this study was developing formulations of H. undatus Haw. jam with pulp and peel, as well as evaluating nutritional compounds and texture properties through sensorial, instrumental, physical, biochemical and microbiological analyses of the final product. The fruit were selected, sanitized, pulped and grinded, and the formulations with different concentrations of pulp and peel (0 – 100%) were developed and evaluated. Microbiological evaluation showed that the formulations are in accordance with the current legislation. The increase in peel concentration in the jam formulations resulted in better consumer acceptance and higher concentration of phenolic compounds, antioxidants and B complex vitamins, such as B1, B5 and B6. In addition, it gave the jams acceptable and pleasant sensorial characteristics and texture.  Adding peel to the formulations enabled us to make total use of the fruit, with no waste, besides making the coproduct richer in compounds that are beneficial to consumers’ health.

The objective was to identify the most frequent causes and threats to nursing professionals in the hospital sector, with regard to occupational health risk. This is a narrative review of the literature, the search took place in June/2019, and digital materials were evaluated in the database of the Occupational Safety and Health Observatory, such as: documents from the Ministry of Economy, Secretary and Inspection of work and a document from the Ministry of Health. 10 studies related to ergonomics in nursing professionals were also selected. Analysis of the materials show data related to the Geographical Distribution of Work Accident Communications; Estimate of underreporting of accidents at work; Economic sectors with higher numbers of notifications; Occupations within the hospital sector; Social security expenses-sickness allowance for work accidents; Most frequent injuries; Parts of the body most frequently affected; Parts of the body most frequently affected by physical exertion; and, Removal from the work environment according to the International Classification of Diseases. It was identified that approximately 60% of cases of ergonomic accidents within the hospital are suffered by nursing professionals. As for the most frequent causes of absence of professionals from the hospital environment, musculoskeletal and connective tissue injuries stood out, followed by fractures, mental and behavioral diseases, as well as dislocations. As for the most frequently affected parts of the body, the fingers stood out. Thus, greater emphasis is needed on sensitizing managers and workers about occupational hazards and their consequences, with a view to reducing exposure to risks and possible damage to health.

The relentless pursuit of competitive advantage in the industrial sector contributes to the realization of the importance of controlling primary production resources. This research is based on the high index of idleness generated by the lack of essential resources for the manufacture of the product, linked to the lack of management of these. The objective of this study is to identify and analyze the production stoppage rates due to lack of raw material, to propose improvements that ensure clear process fluidity and productivity gains for operators, in addition to helping managers in decision making. It is characterized as a case study through direct observation and bibliographic research, in addition to having a mixed approach (quali-quantitative) evidenced by the description of an explanatory research. Data collected in the company were explored to build the solidity of the article, through the numbers of production stops, finished products affected by the lack of material and main items and their respective frequency of absenteeism in the stock. In this way, it was possible to build the ABC curve of finished products and raw materials, allowing the visualization of materials that demand greater attention and care to always keep active in the warehouse, as they are the ones that most rotate in the warehouse. Finally, through the analysis of the information, it is concluded that it is necessary to restructure the material list of the finished products so that it is possible to run the MRP, in addition to the adoption of a routine of rotating inventories based on the ABC Curve of inputs to generate accuracy indexes and ensure control of processes.

Environmental education, in a formal and non-formal environment, is crucial for promoting environmental awareness in the community. Through actions with scientific dissemination, it can be transformative, impacting economic, social and environmental factors. Regarding issues that affect public health and cause environmental impacts, basic sanitation stands out. In Brazil, part of the population is not assisted by a basic sanitation network, resulting in improper effluents disposal and consumption of untreated water. In this sense, sewage treatment by root zone, as a sustainable alternative, has increasingly demonstrated its effectiveness and low cost of implementation, however it is not well known. Thus, this study aimed to use environmental education to disseminate knowledge about the relevance of sewage treatment by root zone. Initially, an online diagnosis was conducted about the knowledge of effluent treatment with high school students from a public school in Paraná. The results revealed that many of the students were unaware of the root-zone technique, making it difficult to assert the answers. Remarkably, it was realized the great need for the development of educational actions on the topic. Thus, an informative Flyer on the theme was created in order to fill some gaps identified with students. Finally, it is suggested that more Environmental Education actions about this theme be implemented, in the most diverse forms of communication, with a view to scientific dissemination and awareness of the population regarding the importance of the correct treatment of effluents, in favor of the preservation, conservation of the environment and quality of life.

Objective: Conduct an integrative literature review about the management tools used in the Stroke Care Line. Methodology: For the articles selection, the following databases were used: LILACS (Latin American Literature in Health Sciences), MEDLINE (National Library of Medicine), SCOPUS - Multidisciplinary database and CINAHL (Cumulative Index of Nursing and Allied Health Literature), in English, Spanish and Portuguese. The research took place from November 2020 to April 2021, using the controlled descriptors in English "Management Decisions" and "stroke", mediated by the Boolean operator "and", aiming to expand the number of studies. The descriptors were extracted from the DECS (Health Sciences Descriptors) of the BVS Portal, the MESH (Medical Subject Headings) of the National Library, and the CAPES / MEC Journal Portal. Results: Education technologies were the most found in the literature compared to innovative technologies, such as: pamphlets, booklets and lectures, showing relevance for facing the patient and the community, contributing to the early identification of the first signs and symptoms, which can still be considered a challenge in this work. Conclusion: It is possible to improve the quality of life of stroke patients through the existence of managerial technology tools that guarantee a fast and effective communication between the multidisciplinary team and the management of health services.

Objective: To identify the sociodemographic and clinical characteristics of users with Chronic Noncommunicable Diseases (NCDs) treated at a hospital emergency service. Methodology: This is a quantitative cross-sectional survey, carried out on the electronic medical record of 364 patients diagnosed in at least one of the four main groups of NCDs, according to the International Classification of Diseases (ICD), in an emergency service of a hospital highly complex public located in the northwest of the State of São Paulo. Descriptive statistics were used for data analysis. Results: There was a predominance of male patients (53.3%), married (56.0%), with incomplete elementary education (49.2%) with an average age of 62.7 years. The most prevalent diagnosis (77.7%) was cardiovascular diseases (CVDs). The comorbidities most frequently associated among study participants were Systemic Arterial Hypertension (SAH) (31.9%), followed by smoking (22.3%), dyslipidemia (19.2%) and alcoholism (16.5%). Of the study participants, 80.4% had complications related to their main diagnosis, the main complication being previous stroke (18.4%). The most used medication for treatment among the participants was the class of antihypertensive drugs. In addition, extensive errors were found in the records of users' medical records, resulting in underreporting. Conclusion: Knowing the profile of users who attend hospital emergency services becomes essential considering that it is often the aggravation of NCDs, which could be minimized if there was a more effective monitoring of the user in Primary Healthcare, reducing unplanned hospitalizations, as well as spending and overcrowding of emergency services.

The Coronavirus disease 2019 (Covid-19) pandemic has become emergent and central to communications on social media, in which several perspectives and conceptions intertwine and oppose, sometimes creating rumors and fake news. The message flow of social media can be studied within the theoretical framework of social representations. For this purpose, 300 messages about Covid-19 were gathered: 100 of individual profiles, 100 of governments and 100 fake news. An analysis of thematic content has been conducted on the three corpora. Divergently from the other means of communication, it may be observed that the fake news results are about the Chinese origin of the virus, offer homemade advice for prevention and cure of the virus and are prone to contest social isolation. Messages from individual and governmental profiles are mostly not about the origin of the virus but provide advice on hygiene practices, garbage disposal, physical activities, psychological care and defend social isolation.

The aim of this study is report an experience with high school scientific initiation students, in Fortaleza-CE, about environmental sustainability during a pandemic by COVID-19. The first stage was based on thematic workshops on theoretical and practical learning with high school students from the school mentioned, in addition, there was the development of didactic material. The themes covered by the workshops were: “Environmental sustainability: what is my role in society”; “Citizenship and society in the context of the School and University”; “Management and management of solid waste in health services”; “Management of radiological waste in dental services”. The second phase consisted of conducting a situational analysis on knowledge and attitudes about the theme of environmental sustainability with students from the first to the third year of the school as public, the “Google Forms” Platform was used as a tool. The situational analysis on the perception of high school students about environmental sustainability allowed us to observe that the students pointed out important reflexes caused by the pandemic resulting from the new coronavirus.

There is sufficient evidence to support a relationship between the severity of periodontal disease and COVID-19 infections. This relationship may be caused by an increase in the immune response mediated by Galectin 3 (Gal-3) and an increase in viral adhesion. Thus, unsatisfactory and poor hygiene conditions determine risk factors in the worsening of the disease. The objective of this study was to analyze the oral hygiene index in patients diagnosed with COVID-19 admitted to the ward of a referral hospital in the metropolitan region of Santa Rita (Paraíba). This study can relate oral inflammatory problems and their outcome in the evolution of patients with COVID-19, contributing to a planning of continuing education actions in oral health care, and to a better evolution of patients with COVID-19. For data collection, a google forms form was used, built by the research team, based on the Oral Hygiene Index in Critical Patients (OHICP), with modifications. In the assessment of the oral hygiene condition of patients with COVID-19, it was observed that 74.1% of the patients presented unsatisfactory and / or precarious oral hygiene. Patients with COVID-19 presented more frequently tongue coating (74.3%), visible biofilm (41.6%) and food remains (35.5%). Poor oral hygiene can aggravate clinical conditions, worsening the outcome regarding the treatment of patients with SARS-CoV-2.

Objective: To analyze the use of Health Surveillance tools by managerial nurses in the planning and evaluation process of Family Health Strategy teams in Northeastern Pará. Methodology: Qualitative study with 7 Nurses of Family Health Units. An interview and analysis using the Bardin and IRAMUTEC methods was performed using the Descending Hierarchical Classification and similarity analysis, producing six lexical classes represented in Dendograma, considering words with significance (p>0.05), according to total frequency (f) and chi-square (x²). Results were expressed in Dendrograma, tree of similarity and cuts of the interviews in matrix frames. Results: We obtained the cleavage of 151 text segments, taking advantage of 76.16%, 5361 words, 633 active, 95 supplementary and average of 35.5 per follow-up. Based on the similarity analysis, the word "No" is perceived as the central nucleus, linked to "Health Surveillance", "Health" and "Action", thus inferring a denial, lack, absence and/or a problematic in the analyzed context. Conclusion: The decentralization of responsibilities between municipalities did not allow performance to meet demands. The non-adherence, in the management and health care models, of the Health Surveillance tools in the Family Health Units of  Northeastern Pará is evident, therefore, the non-adjustment of actions and services in the Family Health Strategy considering local characteristics.

Extensive treatments can eventually be challenging. Even more so when the patient has limitations such as extensive tooth loss and skeletal changes, including overgrowth of the lower jaw. When indicated, these treatments tend to discourage patients due to the history of previous failures. Therefore, in addition to an interdisciplinary dental team composed of oral and maxillofacial surgeons, and prosthodontists, a nutrologist, a speech therapist, and a psychotherapist were involved in the treatment of this case. A 52-year-old female patient, Angle Class III malocclusion, with few teeth and extensive maxillary bone loss, attended the dental clinic of the Brazilian Association of Dentistry in Uberlândia. The treatment involved reverse planning, extraction of the dental remnants, calvarial bone grafting, placement of 6 titanium implants (Neodent) in the maxilla (upper jaw) and 5 in the mandible (lower jaw), orthognathic surgery, and installation of implant-supported fixed complete dentures in both jaws. Furthermore, psychotherapeutic and nutrologist’s interventions were necessary during the dental treatment, concluding the treatment with speech therapy. Within the limitations of this case, the multidisciplinary approach proved to be efficient. It promoted the reestablishment of the stomatognathic system functions without compromising nutrition during the periods when it was impossible to wear prostheses for better healing of the tissues.

The production of ecological materials is being encouraged, aiming to minimize environmental impacts and promote greater sustainability. Therefore, this work aimed to develop bio-polyethylene biocomposites (BioPE)/wood flour (WF), using polyethylene grafted with maleic anhydride (PE-g-MA) as a compatibilizer. The biocomposites were prepared in a corrotational twin screw extruder and injection molded. The properties of Izod impact strength, tensile strength, Shore D hardness, Heat Deflection Temperature (HDT) and water absorption were investigated. Impact strength improved when biocomposite BioPE/WF was made compatible with PE-g-MA. This increase was more expressive for 10% of PE-g-MA with a high degree of maleic anhydride grafting, indicating a higher level of interaction between the phases. The BioPE/WF/PE-g-MA biocomposites showed improved elastic modulus, tensile strength, Shore D and HDT hardness, compared to the non-compatible biocomposite. An important aspect was the reduction of water absorption for biocomposites compatible with PE-g-MA, suggesting a greater barrier effect for the diffusion of moisture. From the point of view of the degree of grafting of maleic anhydride in PE-g-MA, in general, impact strength was the most sensitive property. The results indicate that wood flour is a waste with the potential to be reused in the development of biocomposites.

Potassium bromate (KBrO3) is an oxidizing agent synthesized from bromine with potassium hydroxide, forming a salt with excellent technological and economic results when used in the production of bread, particularly of the French type, as it acts in strengthening the chain of gluten, being possible to incorporate a greater volume of air in the mass, thus improving the final result. However, since 2001, its use in Brazil has been banned, as it was discovered that this salt has a high carcinogenic and genotoxic potential. The analysis of potassium bromate is very important, as it provides information on the bromate residue present in the final product, due to its application in the bakery sector which, despite being illegal, can still be identified, given the advantage of its use in relation to substances legally used for the same purpose. Whether due to lack of inspection, lack of good manufacturing practice or due to soft laws. In this sense, this work aims to identify KBrO3 in French breads in the city of Belém, State of Pará, through experimental qualitative analysis using a direct method. Twenty (20) random samples from supermarkets and bakeries from different neighborhoods were analyzed, of which 17 (seventeen) showed a positive response for the presence of residual bromate. Therefore, it is evident that this additive is still part of the French-type bread production routine putting the consumer's health at risk.

In the search for knowledge about fish health, understanding ecological interactions is essential, but for a long time there was neglect in studies on parasites that affect them. The work with fish pathogens in the State of Maranhão is still insufficient and for this reason this work comes with the objective of conducting a survey of scientific researches developed in the period from 2010 to 2020 on those of pathogens in fish from natural environments and from cultivation of this state. The systematic search for scientific articles on the Web of Science, Google Scholar, Pubmed, ASFA, Scopus and SciELO platforms was used as methodological strategies, in the period from 2010 to 2020, in order to gather information on the topic under study. The results were separated by category of etiological agents due to the diversity of classes and different techniques used in the surveys surveyed. The data obtained show that the fish may be affected by ectoparasitic crustaceans, bacterioses, nematodes, protozoa, myxosporids, fungi, monogenoids and viruses, however in Maranhão the research with these fish parasites is still incipient, in this sense the need for more studies on fish health in this region. In addition, detailed studies on the life cycle of parasites and their transmission routes in order to prevent infections, as well as the construction of an action plan with treatment, control and prevention strategies for these pathologies will be of great relevance in future studies and environmentally sustainable.
